"There is a problem with your input."

[namedgraph]

I'm scratching my head about this because the build works in MacOS 12.6.1 terminal but fails in NetBeans as well as GH action:

[INFO] Running 'npx @rmlio/yarrrml-parser -i /home/runner/work/bkg-streaming/bkg-streaming/beam/target/test-classes/mapping/./beamery/smth/smth/Something.yml -o /home/runner/work/bkg-streaming/bkg-streaming/beam/target/test-classes/mapping/./beamery/smth/smth/Something.ttl' in /home/runner/work/bkg-streaming/bkg-streaming/beam
[INFO] There is a problem with your input.
...
Error:  Failed to execute goal com.soebes.maven.plugins:iterator-maven-plugin:0.5.1:iterator (parse-yml-mappings) on project beam: Failed to run task: 'npx @rmlio/yarrrml-parser -i /home/runner/work/bkg-streaming/bkg-streaming/beam/target/test-classes/mapping/./beamery/smth/smth/Something.yml -o /home/runner/work/bkg-streaming/bkg-streaming/beam/target/test-classes/mapping/./beamery/smth/smth/Something.ttl' failed. org.apache.commons.exec.ExecuteException: Process exited with an error: 1 (Exit value: 1) -> [Help 1]

Any idea where the There is a problem with your input. message is coming from/what it means?

The plugin config looks like this:

I have no idea. I'm pretty sure it's not from this plugin!
