Description

If we make an odata api call with query parameters included (for example ?$top=2) as per the uri specification in odata documentation (https://www.odata.org/documentation/odata-version-2-0/uri-conventions/) with content type as "application/xml" in headers then the response object is coming in "application/xml" format which is expected but If there any error by any case then the error response format is always coming in "application/json" format instead of "application/xml".

  The expected error response format should always match the requested content type which is "application/xml" in my case.

 

for example :

Current Error Response with Content Type = application/xml and Accept = application/xml

{
"error":

{ "code": null, "message": "Cannot find EntitySet, Singleton, ActionImport or FunctionImport with name 'XXXXXX'." }

}

Expected Response should be :

Expected Result:
<error xmlns="http://docs.oasis-open.org/odata/ns/metadata">
<code>null</code>
<message>
Cannot find EntitySet, Singleton, ActionImport or FunctionImport with name 'XXXXXX'.
</message>
</error>

Please kindly look into this issue as it is blocking my release.
