Why does FastApi generate a 422 error when attempting to include a file upload?

edit

FastApi generates a 422 error when attempting to include a file upload because the request data is not properly formatted or is missing required information. This can occur when the file is not included in the correct format or is missing some necessary metadata such as content type or filename. Additionally, this error can also occur if the server is unable to process the file due to insufficient memory or processing power. In order to resolve this issue, ensure that the file is in the proper format and includes all necessary metadata before attempting to upload it.
