Hi, I am trying to implemented this blog and so far have successfully completed till version controlling. However, I get an error when I am trying to import the flow in the PG. The prompted error says that FlowID does not exists in Bucket ID whereas I can see that the specific flow is present in the nifi registry in the UI. Can anyone help explain why this is happening? Additional info: Nifi version: 1.20.0 Nifi registry: 1.22.0 (securely connected to Nifi and buckets are given access to the CNs) Log: Error retrieving flow snapshot: An unexpected error has occurred. Please check the logs for additional details. at org.apache.nifi.registry.client.impl.AbstractJerseyClient.executeAction(AbstractJerseyClient.java:117) Caused by: javax.ws.rs.InternalServerErrorException: HTTP 500 Internal Server Error o.a.n.r.web.mapper.ThrowableMapper An unexpected error has occurred: java.lang.NullPointerException. Returning Internal Server Error response.

Hi, Nifi version: 1.20.0 I have created a bucket in NIfi registry, started version control of a workflow on it, and made several version inside it as well. What I am trying to achieve now is that I want to import one of the versions from it in another processor group on the same Nifi server. However, I get below error of bucket and flow not found: even though I can see the Bucket and different versions inside it on Nifi Registry. Note: my log file is showing me this error: ERROR [NiFi Registry Web Server-93] o.a.n.r.web.mapper.ThrowableMapper An unexpected error has occurred: java.lang.NullPointerException. Returning Internal Server Error response. Has anybody experience this same error? Looking fwd to any feedback. Thanks.

@MattWho thanks for your response. I followed the documented way to switch between flow persistence providers but still getting an error however, a different now: I am witnessing that if I commit and push changes to my Git repo using VS Code, the error I mentioned in my last message disappears, however, using UI when I try to commit changes, it is now showing me above error. In all, I am unable to commit changes to my flows when it is linked with to a Github repo. I am wondering if this functionality that I am trying is even possible? If it helps, my nifi-registry-app logs are rotating between these two kinds of errors when I make any changes in my workflow: An unexpected error has occurred: org.apache.nifi.registry.flow.FlowPersistenceException: Git directory <path to git directory on my local machine> is not clean or has uncommitted changes, resolve those changes first to save flow contents.. Returning Internal Server Error response. I commit and push changes through VS Code (success) since NiFi UI throws error. Then I try to redo "commit local changes" from NiFi UI, it gives below error in my log file. Flow version is not added yet, can not be serialized.. Returning Conflict response. Looking forward to any guideline. Thanks.

Hi, My issue related to committing workflow changes onto my Github repository. I have made changes in the providers.xml file and now my Nifi flows are linked to Github flowPersistenceProvider. However, when I try to commit changes to the same linked repo, it gives me below error: and in the log files, it says: "Flow version is not added yet, can not be serialized.. Returning Conflict response." I also witnessed on "show local changes" that the prompt gives an error "version must be greater than 1". Are these linked? Any guideline would help. Thanks.

Hi all, I have been trying to store my Nifi workflows (via Nifi Registry) onto Azure Devops. I need little help in identifying the appropriate "flowPersistenceProvider" for Azure Devops that needs to be modified in providers.xml file. Ps: so far, I have connected Nifi Registry to Github and its a success. I need same functionality for Azure Devops now. Looking forward to any guidelines.
