HTTP Status Code 422
Status code 422, also known as "Unprocessable Entity", is an error code used in communication between web servers and clients. It indicates that the server understands the format of the request you sent (like a form submission or API call) but there's something wrong with the data itself.
Here's a breakdown of what a 422 error means:
- The server understands the request format: Unlike other error codes like 400 (Bad Request), the server recognizes the type of information you sent.
- The data itself is wrong: There are errors in the specific details of your request. This could be due to missing information in required fields, invalid data formats (like an email address in the wrong format), or violations of set rules (like trying to register with an already used username).
In simpler terms, imagine you're filling out a form. The 422 error would be like the form highlighting the specific fields where you entered wrong information, rather than saying you filled out the entire form incorrectly.
