I'm trying to get the contactInformation object on a Contact object on the REST API in BC. Trying to use the $expand with this URL - localhost:7048/.../contacts
This is giving this error:
{"error":{"code":"Application_DialogException","message":"id type not specified. CorrelationId: 0db092c6-f3fd-45c9-a88b-2f566184db49."}}
According to the EDMX, this $expand should be valid so, I'm not sure what's going on here?
Any help would be great! TIA
