Hi experts,
I am using the POSTMAN for D365 REST API tests. At the time of PATCH request, I got the success status (204:No Content) but doesn't update the actual data & no error too. Here I add the reference screenshots,

At the same, the field 'PositionId' become non editable, which am trying to update.
Also I tried the another non editable field 'PersonnelNumber' for confirmation (Is that prevent update), then the response showed the actual error. Here the shots,

In this request 'PositionId' used as an entitykey. Not only this one but also the all request shows the '204:No Content' status response if trying to PATCH entity key even it non editable field.
Also tried the x++ job to do the above same showed the actual error exactly what I want ('PositionId is read only').
Is there any solution to retrieve the correct error message?
Any help should be appreciate.
Thank you.
