422 HTTP Status Code: What It Is and How to Fix It?

The HTTP 422 status code, also known as the “Unprocessable Entity” status code, is a client error response code that indicates that the server was unable to process the request due to invalid data. This can happen for a variety of reasons, such as:

• The request body contains invalid data.
• The request body does not match the expected schema.
• The request body is missing the required fields.

When a client receives a 422 status code, it should not retry the request without making some changes to the request body. The specific changes that need to be made will depend on the reason for the error.

Here are some tips for fixing 422 errors:

• Check the request body for invalid data.
• Make sure that the request body matches the expected schema.

}
