Issue with Added NARs in MiNiFi/EFM - New processors unpacked but not recognized

[#1]

Hello Everyone,

We are currently conducting tests  to read data from CDC Debezium-enabled postgreSQL database and write to Azure EventHub.

Actions performed:

We uploaded three NARs needed to use the put

• We added the following NARs as extensions:

  • nifi-azure-nar-2.4.0.nar

  • nifi-azure-services-api-nar-2.3.0.nar
  • nifi-cdf-debezium-postgresql-nar-1.28.1.2.1.7.2006-1.nar

• After a manifest refresh in EFM, we were able to see and use the PutAzureEventHub and 

  CaptureChangeDebeziumPostgreSQLprocessor processors.

• We then configured the flow, published a new version, and confirmed that the flow was successfully pushed to MiNiFi.

Issue

The Flow is pushed to MiNiFi but it is not being validated, thus the publish request fails, we have errors as if the newly added processors are not recognized, I believe?

2026-04-02 12:22:09,379 INFO [MiNiFi logging handler] org.apache.nifi.minifi.StdOut 12:22:09.379 [Validate Components Thread-3] DEBUG org.apache.nifi.controller.AbstractComponentNode -- Computed validation errors with Validation Context StandardValidationContext[componentId=9706f422-72e7-4ee9-b7e5-525fab338432, properties={}]; results = ['Missing Processor' validated against 'Any Property' is invalid because Processor is of type org.apache.nifi.processors.azure.eventhub.PutAzureEventHub, but this is not a valid Processor type]

However, In the logs it seems the NARs have been unpacked and we can see the unpacked files.

I tested deploying a flow that uses only the default MiNiFi processors. The flow validated successfully, and MiNiFi started without any issues.

Below are curated entries from the minifi-bootstrap.log file related to the added NARs:

Environment Details:

• MiNiFi version: Java 2.24.08

• EFM version: 2.2.0.0-86

• All NARs were downloaded from the Cloudera Sonatype Nexus repository.

I  do not understand where the issue comes from.
I would really appreciate your help

Best regards,

Hello Everyone,

We are currently conducting tests  to read data from CDC Debezium-enabled postgreSQL database and write to Azure EventHub.

Actions performed:

We uploaded three NARs needed to use the put

• We added the following NARs as extensions:

  • nifi-azure-nar-2.4.0.nar

  • nifi-azure-services-api-nar-2.3.0.nar
  • nifi-cdf-debezium-postgresql-nar-1.28.1.2.1.7.2006-1.nar

• After a manifest refresh in EFM, we were able to see and use the PutAzureEventHub and 

  CaptureChangeDebeziumPostgreSQLprocessor processors.

• We then configured the flow, published a new version, and confirmed that the flow was successfully pushed to MiNiFi.

Issue

The Flow is pushed to MiNiFi but it is not being validated, thus the publish request fails, we have errors as if the newly added processors are not recognized, I believe?

[#3]

Hi YSFSK! Thanks for the detailed post and the logs. While we wait for one of our MiNiFi experts to weigh in on the specific errors you're seeing, you might find some clues in the Custom NAR Configs documentation.

Also, this community thread on Ghost Processors covers similar 'Unknown bundle' issues. Hope this helps get you started!

[#4 · Accepted solution]

Hello @YSFSK, 

MiNiFi version you have is compatible with CFM 4.2.0, which is based on NiFi 2
https://docs.cloudera.com/cem/2.2.0/release-notes-minifi-java/topics/cem-java-agent-processors.html

You mentioned you downloaded nifi-cdf-debezium-postgresql-nar-1.28.1.2.1.7.2006-1.nar
that is for NiFi 1.28. 

I checked and the nar is available for different 2.x versions, so you should select one that it matches your NiFi version. 

Do the same for the other two NARs, they are 2.4 and 2.3, so just make sure they match the actual version. 

[#5]

Hello @vafs,

Thank you for your reply.

I attempted to test the same Debezium NAR with a more recent version, however, we were unable to upload new extensions to EFM.

I understand your point regarding the use of an older Debezium NAR version.
However, we also conducted tests using a separate class and flow that included only the two Azure NARs (both are above 2.3 in versions) without the debezium processer & nar (About a year ago, this same flow and exact NARs worked with the exact same MiNiFi image currently tested).

For this reason, I believe the issue may not be solely related to the Debezium 1.x NAR, as the EventHub processor is also affected.

Hello @YSFSK, 

I do not understand part of your response. 

---

I attempted to test the same Debezium NAR with a more recent version, however, we were unable to upload new extensions to EFM.

Why you were unable to upload it? Any errors?

I understand your point regarding the use of an older Debezium NAR version.
However, we also conducted tests using a separate class and flow that included only the two Azure NARs (both are above 2.3 in versions) without the debezium processer & nar (About a year ago, this same flow and exact NARs worked with the exact same MiNiFi image currently tested).

For this reason, I believe the issue may not be solely related to the Debezium 1.x NAR, as the EventHub processor is also affected.

On the first part you say that tested only with the two Azure NARs on 2.3, which should be good for your version, without the Debezium 1.x, and it worked. 
Which makes sense that this points to this Debezium 1.x NAR only as it is created for a different version. 

On Sonatype Nexus Repository I do see Debezium 2.3 version, that is the correct for your environment. 

[#7]

Hello @vafs,

I see how my earlier explanation may have been confusing, so I’ll focus firstspecifically on the current tests.

We ran two separate flows:

1. Flow with Debezium NAR + two Azure NARs
   This resulted in the errors previously shared in this topic, affecting both the CDC processor and the PutAzureEventHub processor.
2. Flow with only the Azure NARs
   This flow simply generates text and sends it to Event Hub. However, it also fails with the same “not a valid processor type” error for the PutAzureEventHub processor.

So, even without the Debezium 1.x NAR, we are still encountering the same issue with the Azure processor.

Hello @YSFSK, 

I understand now. I do see the error you mention: 

2026-04-02 12:22:09,133 INFO [MiNiFi logging handler] org.apache.nifi.minifi.StdOut 12:22:09.133 [pool-15-thread-1] DEBUG org.apache.nifi.controller.serialization.VersionedFlowSynchronizer -- Could not find a compatible bundle for org.apache.nifi:nifi-azure-nar:2.4.0 type org.apache.nifi.processors.azure.eventhub.PutAzureEventHub

That error points to be a problem with the version. 
So we are basically on the same point. 
We have nifi-azure-nar at 2.4.0, nifi-azure-services-api at 2.3.0 and nifi-cdf-debezium-postgresql at 1.28.1. 
This is a mix that is not working.

I do not know the NiFi version you have, but should use that version for all the NARs as well. Using different versions is not a good idea. 
You can download them from the Sonatype Nexus Repository.

Hi, I had to downgrade and upgrade all my nars to 2.0.0 for it to work.
