What Operating System are you using (both controller, and any agents involved in the problem)?

jenkins 2.401.2 from docker image
And latest jenkins-ssh agent LTS jdk11 for the agent

ERROR: Exception when publishing, exception message [argument "outputFile" is null]

Anything else?

Sometimes the artifact is published, sometime not.
Downgrading to 1.24 solve the issue.

Not sure if it comes from this plugin or a dependency ... if I can help don't hesitate.
For the time being, I keep with 1.24 so everything still work

Thanks for your effort.

I have the same error, and all configuration is okay.
