BAQR7073E The service response property {0}, which is mapped to header {1}, is missing from the service response body for API {2}.
Explanation
The header is required, but a value cannot be assigned unless the mapped service response property is present in the service response body.
User response
Ensure that the mapped field is included in the service response body. The service might have been updated after it was imported into the API. The updated service archive needs to be re-imported into the API.
