Anything else?

This is reproducible with main branch as well. On debugging the issue https://github.com/jenkinsci/jenkinsfile-runner/blob/98f3b6911edacbeb7f97111bac9f83ea0785622d/payload/src/main/java/io/jenkins/jenkinsfile/runner/PipelineDefinitionProvider.java#L38 returns empty list instead of the two implementations it is supposed to return.

I reviewed https://github.com/jenkinsci/pipeline-as-yaml-plugin/issues/28 but this issue happens even before SetJenkinsfileLocation.
