def update_processor_attribute(root_pg_id,Json_props,Processor):
    proApi = nifi.apis.processors_api.ProcessorsApi(api_client=None)
    propsDto = models.processor_config_dto.ProcessorConfigDTO(properties=Json_props)
    proDto = nifi.models.processor_dto.ProcessorDTO(id=Processor.id,parent_group_id=root_pg_id,config=propsDto)
    proEntity = nifi.models.processor_entity.ProcessorEntity(revision=models.RevisionDTO(version=Processor.revision.version+1),component=proDto)
    proApi.update_processor(Processor.id,proEntity)
what I noticed from my script that did the upgrade is that when I add 1 for version it work for the one that is already created in nifi, but when I add processor with API and same time I do update it was not working !!
Urgency
Please give a brief description of how critical this issue is to you.

For example, if it's blocking your Production environment, or perhaps you are just notifying us of something you found but isn't blocking your workflow.
Please Mr @Chaffelson we need you help,
          
nipyapi.canvas.update_processor doesn't currently have a refresh flag, which would be a good addition to make this work better.

Generally the process is to fetch the current revision using a get_processor command, then supply that with the next call. I do not think it needs to be incremented manually.
Is there a reason why you aren't using nipyapi.canvas.update_processor ?
