@Kiranq  Nothing stands out to me as problematic in the diagnostics output that relates to the stick FlowFile.  The verbose output indicates just 1 queued FlowFile on the canvas The Diagnostics output then tells us that this one FlowFile is queued in the connection with ID:  d8e8fe6e-38a5-3fee-8933-2e8c6bf55afa The UUID of the queued FlowFile is: ce9cbd21-455b-4191-80bc-6598609b71a1 Details of this One FlowFile:   If you clear out the FlowFile, does the very next FlowFile that enters this Process group get stuck?  Do FlowFiles only get stuck in front of this one specific processor and everywhere else FlowFiles are being processed fine? How is this specific process group configured? Can you list the connection and verify the content of this FlowFile looks correct? Have you tried adjusting NiFi's logging to DEBUG to see if any useful Debug output is produced for the issue? Thanks, Matt ... View more

@Kiranq  This error shared: 2024-10-17 08:35:19,764 ERROR [Timer-Driven Process Thread-5] o.a.n.c.s.StandardControllerServiceNode StandardControllerServiceNode[service=CSVRecordLookupService[id=a8b84b00-b0ee-31c8-dbda-7e7e9795ba4b], name=CSVRecordLookupService, active=true] Encountering difficulty enabling. (Validation State is INVALID: ['CSV File' is invalid because CSV File is required, 'Lookup Key Column' is invalid because Lookup Key Column is required]). Will continue trying to enable. Indicates that NiFi is trying to enable a NiFi Controller services loaded from the flow.json.gz during startup, but cannot because it's configuration is invalid.  It is complaining about the configuration of the "CSV File" and "Lookup Key Column" properties. Have you tried starting your NiFi with the following setting in your nifi.properties file set to "false": nifi.flowcontroller.autoResumeState=false This will start NiFi and all components on the canvas will not be started during startup. Also if you NiFi is at the point it is trying to enable components on the canvas, Your NiFi is up and running. As far as the screenshot error, have you verified ownership and permissions on that directory path.  Permissions can be an issue if you started the NiFI service as different users at some point in time resulting in some files created on startup having different ownership.    Please help our community thrive.

@Abibee04  Please start a new Community question with the details of your query. I am not clear what you mean by "recover the registry", so the more detail you can provide the better in that new community question by sharing what step you performed and what you are looking to accomplish.

If you meant Storing Apache NiFi Versioned Flows in a Git Repository hosted on Azure DevOps, then the steps should be similar to the steps you followed to connect to Github. The appropriate flowPersistenceProvider is GitFlowPersistenceProvider. You can follow the steps as mentioned here: Storing Apache NiFi Versioned Flows in a Git Repos... - Cloudera Community - 248713 Or the video: https://youtu.be/kK7eVppg9Aw   Only changes you would have to do is to generate PAT in Azure DevOps with permissions on code read, write, modify. P.S. The solution is only available for Git under Azure DevOps, and not for TFS. ... View more

@Kiranq, What I found is that the JoltTransformRecord expects only single record to work with hence the name. I noticed when I try to pass an array I was getting the error "...error transforming the first record", however if I pass just one json record it works. If you have an array of json\csv and you are looking to split and process each record individually then I would suggest that you split the records before the JoltTransformRecord. If you dont want to split the array then I recommend using JoltTranformJson first and then use Convert Record processor to convert to CSV. ... View more

If you are getting multiple records in one Json array , then you probably need to use SplitJosn Processor to get each record individually , then extract the values you need using EvaluateJsonPath from each record then do the PutSQL. ... View more

Thanks for the reply. I did it in the same way you have mentioned (I am importing Selenium module and from this module, Service, WebDriverWait and EC components are imported) but late in the code execution, my scripts gives an error "global name Service is not defined". Any idea whats causing the issue? ... View more

Thanks. It was an issue with the connection string. It was pointing to another database while my processor was inserting into another database.  ... View more

@Kiranq  What version of Java is your NiFi using? Sharing the output for your NiFi-Registry configured keystore and truststore in the nifi-registry.properties file would help. Sharing the keystore and truststore configured in your NiFi registry client would help as well. ./keytool -v -list -keystore <keystore or trustsore> You can also use openssl to see what is sent from the server (NiFi-Registry) to client (NiFi) in the initial TLS exchange. ./openssl s_client -connect <nifi-regisry hostname>:<NiFi-Registry port> -showcerts Matt ...

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.
