CostlyOstrich36 I confirm this was the case.

So :

module_a.py @PipelineDecorator.pipeline()... from module_b import my_func x = my_func()
` modele_b.py

@PipelineDecorator.component()
def my_func()
pass `

Under this circumstances, the pipeline is created correctly and run correctly
But when I clone it (or click “Run” and submit) - it fails with the error above.

Moving my_func from module_a to module_b solves this.

To me this looks like a bug or unreasonable and undocumented limitation
