@Rups can you please check if you provided all the required parameters from [1], especially check for the "SSL Context Service" parameter.

Hello @Rups ,

 

thank you for asking this question about NiFi InvokeHTTP.setUpClient throwing IndexOutOfBoundsException.

 

Can you please specify your exact NiFi version, so I can look up the source code.

If the source code of your NiFi version is the same as the code I found, the exception was coming from this line:

https://github.com/apache/nifi/blob/master/nifi-nar-bundles/nifi-standard-bundle/nifi-standard-processors/src/main/java/org/apache/nifi/processors/standard/InvokeHTTP.java#L665

 

My first interpretation is that the issue might be related to SSL. Is SSL fully enabled and configured in your environment, please?

Thank you:
Ferenc

Hi Ferenc, 

 

I am using nifi-1.11.4. The SSL is working for other team members running on the same version.

I am importing the flow from Nifi registry over HTTP. All flows are using parameter context. 

 

Yes, your guess might be correct as without SSL , the processor comes up perfectly.

 

Please let me know what specific information you need regarding SSL. I will get from the platform team. 

 

I do not want to face this situation when flow are deployed on production. 

 

Thanks

Rups.

Hello @Rups ,

 

thank you for marking my earlier post as a solution about suggesting setting "SSL Context Service" parameter to resolve the issue. It is motivating to know when a suggestion actually helps. 🙂

 

Do I understand correctly that your workflow is operating now as expected?

 

Thanks again:
Ferenc
