{"msg":"Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported"

This error message typically means that the server is unable to handle the content type of the request that it received.

In this case, the server is telling you that it does not support the content type 'application/x-www-form-urlencoded;charset=UTF-8'. This is a common content type used in form submissions.

To resolve this error, you can try changing the content type of your request to a supported type. Alternatively, you may need to check with the server administrator or the API documentation to ensure that you are using the correct content type for your request.
