--------------------------------------
Hello [~jbarotin],
Sorry for the delay.
However regarding your fix in OData V4 [8.2.8.7 Preference
return=representation and
return=minimal|http://docs.oasis-open.org/odata/odata/v4.0/errata03/os/complete/part1-protocol/odata-v4.0-errata03-os-part1-protocol-complete.html#_Toc453752234]
it is defined that:
{quote}
In OData, return=representation or return=minimal is defined for use with a
POST, PUT, or PATCH Data Modification Request other than to a stream property,
or to an Action Request. Specifying a preference of return=representation or
return=minimal in a GET or DELETE request, or any request to a stream property,
SHOULD return a 4xx Client Error.
{quote}
So as I understand your case you receive an error if you add {{Prefer':
'return=minimal'}} in a {{GET}} HTTP request.
If yes then this is the behaviour as defined in OData V4.
If not please help me in explain your issue in more detail.
Kind Regards, Michael
