             Summary: Importing flow should handle missing parameter provider
                 Key: NIFI-11039
                 URL: https://issues.apache.org/jira/browse/NIFI-11039
             Project: Apache NiFi
          Issue Type: Improvement
    Affects Versions: 1.19.1, 1.19.0, 1.18.0
            Reporter: Bryan Bende


From Apache Slack:

{color:#1d1c1d}We have been using deployment of Parameter Contexts using Parameter Providers in Nifi v1.18.0. We are also using the NiFi registry to save Processor Groups and restore them into the current flow. There is an issue where if a Process Group is saved with a Parameter Context, that has been created via a Parameter Provider and the Provider has been deleted, the flow fails to deploy saying the provider does not exist. I guess I would expect the behavior to create the Parameter Provider if it doesn't exist, just like when the Parameter Contexts, Controller Services ect. Even if the desired behavior is to not create Parameter Providers, the import from the registry should still fail gracefully and allow the remaining flow to be imported, ignoring the missing Provider. If I get a flow into this state, I either have to find an older version of the flow in the registry to recover, or I need to manually download, modify and re-upload the PG in order to get the flow deployed.{color}
