HTTP error 422 is a part of the HTTP status code family, but it is not similar to 401 or 406 errors. This error occurs when the server understands the request but cannot process it because of semantic errors included in the requested content.
Diagnosing this error can be a bit challenging since it lacks enough information regarding the triggering factors.
However, if you are facing HTTP error 422 While accessing a website, you can experience various implications.
Primarily, it hampers the browsing experience by leading to issues such as data input and validation. Thus, users can’t proceed with activities on a website like submitting forms and updating resources.
Proper exploration and resolution of any status error is crucial to ensure a splendid browsing experience. In this article, we will explain some of the reasons behind the 422 error and ways to fix it within minutes.
Common Reasons Behind the HTTP Error 422
In order to identify the underlying cause of the 422 problem, it is required to investigate many troubleshooting techniques.
The majority of WordPress users get this problem either as a result of semantically erroneous code or a damaged database. However, the following are some typical causes of this error:
Whenever the data provided by the user includes an error in it, the HTTP 422 error can occur. This is one of the most frequent causes of this error.
The mistake or the error can be incomplete fields, incorrect data formats, or data that does not adhere to the server’s set requirements. For instance, when a user submits a form with inaccurate data in it, the server will deny the request and return a 422 error code.
Inappropriate API Usage
When it comes to RESTful APIs, developers utilize HTTP 422 errors to describe the fact that the information provided in the request body does not follow the antedated format.
Moreover, it disobeys the API’s validation guidelines. For example, providing data in a different format can result in a 422 error if an API endpoint needs specific arguments in a particular structure.
Business Logic Violation
When a request does not adhere to the necessary structure and protocols needed by the server, it is said to be malformed. This can be the result of incomplete headers, inadequately structured data, or poorly written URL parameters.
So, the HTTP 422 error comes up when the server gets a request formatted improperly. Thus, the server is unable to determine the client’s purpose.
API Compatibility & Versioning
Since APIs evolve with time, versioning is often included by developers to guarantee backward compatibility. The server will become unable to properly handle the request if the client is using an old or incompatible version of the API. As a result, the 422 error occurs.
Authentication & Authorization
When a client’s request necessitates authentication and authorization, errors in these procedures can result in HTTP 422 status code. Thus, users providing incorrect credentials while logging in can face the error message. Since they don’t have enough permission to access a particular resource.
Input Size Restrictions
Some servers have restrictions on the amount of data that can be entered into a single request. So, when a client enters data that is larger than these limits, the 422 error shows up, informing that the request needs to be altered.
Now, let’s focus on some easy ways to quickly resolve the HTTP error 422 using the following processes.
Manually Fix The Database
You can access the database using the cPanel and repair your database to prevent the 422 error. This manual approach is ideal when you can’t access the WordPress dashboard. Here is the step-by-step process that you can follow:
Log into your cPanel using your credentials and scroll down a bit until you see the Databases section.
Under the database section, click the phpMyAdmin and wait a few seconds.
You will now be redirected to the phpMyAdmin area, where you can see your website’s databases. Look at the left-hand side of the screen, locate your database, and click on it.
Since you are accessing your database from cPanel, you don’t need to provide the database credentials. After getting into your database, you can see all the tables it includes on the right side.
Scroll down a bit, tick mark the Check All button and click the dropdown menu beside it and select the Repair table option and click the Go Button.
Refresh your website to check if the 422 Error is resolved or not. But if the error persists, keep reading to learn more ways to avoid the error code.
Fix The Database Using Plugin
If you want to minimize your effort and are not willing to go with the manual process, then it’s for you. As a WordPress site owner, you can simply install a plugin and resolve the 422 error by fixing the corrupted database tables.
These are the steps you can follow to easily repair your database using a plugin:
Log in and get access to your WordPress dashboard and click Plugin > Add New. Then find WP-DBManager from the search bar, install & activate the plugin on your site.
Now get back to your Dashboard and click the Database > Repair DB option. Select the database tables that you already know are corrupted and click the Repair button at the bottom of the database tables.
Wait for a few seconds for the database table repair process to finish. Now, access the site or page that was showing the 422 error to check if the error is still showing up.
Utilize The WordPress Error Log
It’s time to verify any errors in the underlying files if you’re still getting the HTTP 422 error on your site. Since there are many files on a WordPress website, inspecting each file is not realistic. Thus, you need to enable the error logs using the following steps:
After logging into your cPanel, go to the Files section and click File Manager.
In File Manager, scroll down a bit and click the public_html file.
Now, click the wp-config.php file and then right-click on it and select the edit option.
Insert the following lines of code just before the line saying /* That’s all, stop editing! Happy blogging. */:
If the line define( ‘WP_DEBUG’, true ); already exists in the file, ensure that it reads true. In this case, you only need to add the second line of code define( ‘WP_DEBUG_LOG’, true ); to enable error logging.
When you are done adding the code, save changes to the wp-config.php file and reload the page that was displaying the 422 error. Followed by navigating to the wp-content folder inside the cPanel.
Within the wp-content folder, locate the debug.log file. This file contains the logged errors. Open the deub.log file to explore its content.
A newly created debug.log file won’t include many lines. However, the file will include lines indicating a precise mistake that led to the HTTP 422 response code. Plus, the file name and line number in which the semantic mistakes should also be included in the error message.
Wipe Browser Cache & Cookies
Browser cache and cookies can interrupt the request processing with the server leading to a 422 error. Thus, clearing the browser cache and cookies can fix the error by ensuring the latest data is being served. Here is the process of clearing your browsing data:
Go to your google chrome browser and click the three-dot menu and then click Settings.
Now click Privacy and Security > Clear Browsing data and Check mark the cookies and other site data and also the images. Select the time range as All Time from the dropdown menu. Then click the Clear Data button.
You can also enter chrome://settings/privacy in your browser, which will direct you to the privacy settings. From there, you can clear the browsing data following the previous processes.
Upload Fresh Script Code
The server error that causes the HTTP 422 error can occur when a script is being uploaded. Therefore, uploading a new script can fix the issue if the current script being used to upload is the cause of the error.
Ensure that the new script is well-tested and complies with the server’s specifications, including any required dependencies and supported programming languages. Moreover, the 422 error can be avoided by implementing comprehensive error-handling techniques inside the script.
You need to implement thorough testing in a staging environment before deploying the new file to your production server to find and fix any possible errors.
Furthermore, set up monitoring tools to keep track of performance and quickly handle any potential future 422 errors. A streamlined and dependable uploading procedure can be accomplished by maintaining version control and scheduling frequent upgrades and maintenance.
Contact With The Experts
If you are still facing the HTTP 422 error, it’s time to seek help from your service provider. Their support team will surely help you resolve the issue pretty quickly. Also, you can contact an expert developer who is experienced in handling different sorts of errors.
Either way, they are able to provide specialist counsel, carry out in-depth analysis and provide tailored solutions to resolve the issue. Keep in mind that if your service provider or hosting company is unable to provide you with any solution, you better switch to a different one.
Facing a 422 error can be disturbing, but finding the reason behind it and resolving the issue is not that complicated. We’ve mentioned the easiest processes to minimize your effort in handling the error. Plus, here are some tips to avoid getting the error in the future:
Perform data validation on all user inputs to eliminate the possibility of the server receiving inaccurate or unsuitable information.
Provide helpful error messages whenever a user submits data that does not satisfy the necessary format or limitations.
Ensure that your API queries make use of the right HTTP methods. For instance, the POST method should be used when generating resources, the PUT method when updating existing resources, and the DELETE method when deleting resources.
