Post Cancel operation task Conflict
    [Documentation]    Conflict. 
    ...    The operation cannot be executed currently, due to a conflict with the state of the VNF instance resource. 
    ...    Typically, this is due to the fact that the VNF instance resource is not in STARTING, PROCESSING or ROLLING_BACK state, 
    ...    or another error handling action is starting, such as retry or rollback. 
    ...    The response body shall contain a ProblemDetails structure, in which the �detail� attribute should convey more information about the error.
