How to fix 422 error?

Published on April 7th, 2022

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415(Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

The 422 status code is only used if the server understands the content type of the request entity, and the syntax of the request entity is correct but the server was unable to process the contained instructions. For example, this might be caused by an invalid parameter value in the request body.
