422 Unprocessable Entity
The request body was well-formed but contains semantical errors. The response body will provide more details in the
error parameters. Sending invalid or unknown data results in a
422 Unprocessable Entity response.
The common reason for error 422 is the wrong character within the code.
You also have to be sure that all parameters of the sample code are included. This is how it should look like for the Logistics API.
