Hi Kojo,
you were configuring the test without a ThreadGroup?
It looks like the exception cames when you try to configure all the test outside a Thread Group. We use the ThreadGroup context to share values between components, and in your Trace this context look like didn't exist.
Waiting for feedback.
Regards!

Hi Kojo,
I took a close look to this issue and try to reproduce it. It works fine through the UI and in Server mode. Analysing the stacktrace I saw it looks like a missing Class in your classpath. Can you please verify you don't have twice the plugin jar in your classpath? We change the version number with every ticket so it can appear twice in your lib/ext folder and cause this type of problems. It happens to us.
Regards!

Hi Kojo,
I cannot reproduce this error. Are you still using the same jmx file?
Have you proper configured your Schema Registry with a testing avro?
I need more feedback in order to analyse this error.
I updated master with all fixes and some tweaks, so please try with that branch.
Thanks

Hi Kojo,
Thanks for the feebback
We are gonna take a look and try to reproduce the error, we'll let you know.
Is possible if you attach a jmx file?
Thanks!

Umm.. actually I have tried with the Example-Test-Plan.jmx file this provide.
It seems the file have a ThreadGroup.

kszosze commented on August 25, 2024

Ok, i'll check up the example test plan, probably the issue is in there.

kszosze commented on August 25, 2024

Hi Kojo,
I just checked the Example-Test-Plan.jmx, running here and didn´t get the same error. Guess you didn´t change anything and just open the Example-Test-Plan with a Schema Registry running in your local and some schemas there? Or what is your setup?
Regards.

Hi Jose,
Thanks for replying.
I should have told you the environment ran the Jmeter.

The Jmeter was in a pod of Kubernetes as Ubuntu container which I made using Dockerfile.
And I ran jmeter with jmeter -n -t Exaple-Test-Plan.jmx in which I changed Schema Registry Url to Kubernetes service url.

Hey Kojo,
Thanks for the reply and clarify the environment. Indeed it will help.
I´ll try to reproduce your environment and giving a try.
Just to know, Did you change the Schema Url in the JMX or tried to do it through env variables?
Regards!

from kloadgen.

kszosze commented on August 25, 2024

Hi Kojo,
I think I got the issue and a patch in the branch linked to this ticket.
Do you mind to test it in your environment?
Thanks for the feedback!
Cheers

Thanks to care !
It is not urgent now so have a enough time to look around Jose !
I will look around the code also.

HI Kojo,
thanks for the feedback, I really appreciate it.
If you don´t mind, we keep a policy about one issue one problem, so I can merge the code and solve problems asap for other people, instead of accumulate then in one task.
Do you mind open a new one with last one, we will try to jumo over asap.
In the other hand, I recommend use the jmeter gui editor to make all the changes. Some times manual ones screw the file, looks like it´s a bit peaky with that.
Thanks!!

Hi Jose,
Thanks for the effort.

I don't mind what you're going to do.

Have a good day !
