GetFile failed to start : java.lang.IndexOutOfBoundsException:

Rups — Tue, 07 Apr 2020 05:29:02 GMT

Attached is the java stack. I am getting this error in the nifi.log whenever i am starting GetFile processor which is first processort in my list.

2020-04-07 01:17:01,371 ERROR [Timer-Driven Process Thread-5] o.a.nifi.processors.standard.InvokeHTTP InvokeHTTP[id=51048885-0171-1000-9a41-00f55a11ae71] Failed to properly initialize Processor. If still scheduled to run, NiFi will attempt to initialize and run the Processor again after the 'Administrative Yield Duration' has elapsed.

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

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

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
