            Error: The operation cannot be executed currently, due to a conflict with the state of the resource.
            Typically, this is due to the fact that the VNF instance resource is in NOT_INSTANTIATED state,
            or that another lifecycle management operation is ongoing.
            The response body shall contain a ProblemDetails structure, in which the "detail" attribute shall
