Is assignment of mandatory module types to distribution set types working?

[fkromer]

ATM we try to assign mandatory module types to distribution set types using POST /rest/v1/distributionsettypes/{distributionSetTypeId}/mandatorymoduletypes. Can you confirm that it's working? With request body (raw, json, id==1 matches existing sw module type)

{
    "id": 1
}

I get

{
    "exceptionClass": "org.eclipse.hawkbit.rest.exception.MessageNotReadableException",
    "errorCode": "hawkbit.server.error.rest.body.notReadable",
    "message": "The given request body is not well formed"
}

as response? Would not be dramatic if it would be missing... just good to know.
