I get this exception whenever i try having a baseresponse of type
The example endpoint can be annotated with:
this will cause an exception on generating the openapi docs:
GuidGuidThe example endpoint can be annotated with:
[ProducesResponseType<MyResponseWrapperClass<Guid>>(StatusCodes.Status200OK, MediaTypeNames.Application.Json)][ProducesResponseType<MyResponseWrapperClass<Guid>>(StatusCodes.Status200OK, MediaTypeNames.Application.Json)]this will cause an exception on generating the openapi docs:
