Unexpected end of JSON input: Code 422

A 422 Unprocessable Content error will occur when the server understands the request being made and the syntax is correct, but it is unable to process the request’s instructions [1].This can point to a wide variety of potential issues that may be occurring with the request. There are several reasons why this could occur, one of them being that the server has not received the required header, cookies or query strings required to process this request.

Error 422 is an HTTP code that tells you that the server can’t process your request, although it understands it. The full name of the error code is 422 “unprocessable entity.” See how Kinsta stacks up against the competition.

In a nutshell, the error means that you’re making a request the server understands, but it can’t process it. Typically, this happens because there’s a semantic error somewhere in the request, usually within a PHP or JavaScript file.

Unlike other HTTP errors, the 422 code will keep reappearing until you manage to troubleshoot the problem with your request. However, this can be difficult since the error doesn’t provide specific information about what part of the request it can’t process.

HTTP 422 could be caused by the 403 Access denied. HTTP 403 (Access Denied) occurs during upload of the documents normally when there is file size issue.

The error message here is what sticks out to me: Unexpected end of JSON input - the input that was sent in the API call wasn't correct. It would help if you could post the JSON that was the cause of the error.
