#3588 [BUG] No Flyte Entities Detected with Ray example Jupyter Notebook workflow registration Issue created by peterklingelhofer Describe the bug Using the example Jupyter Notebook file found here: https://docs.flyte.org/projects/cookbook/en/latest/auto/integrations/kubernetes/ray_example/ray_example.html When I try to register the

ray_example.ipynb

file's workflow, I get this output:

pyflyte register workflows --project repo --image localhost:30000/$FLYTE_DOCKER_IMAGE_TAG
Running pyflyte register from ~/Dev/repo with images ImageConfig(default_image=Image(name='default', fqn='localhost:30000/repo', tag='imageTag'), images=[Image(name='default', fqn='localhost:30000/repo', tag='imageTag')]) and image destination folder /root on 1 package(s) ('~/Dev/repo/workflows',)
Registering against localhost:30080
Detected Root ~/Dev/repo, using this to create deployable package...

Computed version is kChHd1ibpkx7jpAR1MIWIg==
Loading packages ['workflows'] under source root ~/Dev/repo
Successfully serialized 0 flyte objects
No Flyte entities were detected. Aborting!

The

ray_example.ipynb

runs fine locally as we'd expect, it's just when attempting to register the workflow do we run into problems. Expected behavior I would expect this to work the way the python example (downloadable from that same page in the docs) works:

Additional context to reproduce I noticed that VS Code thinks there is a

\n

after

@workflow

(unsurprising as Jupyter Notebooks are typically run in the browser obviously), not sure if that could be causing the problem. Screenshots Are you sure this issue hasn't been raised already? ☑︎ Yes Have you read the Code of Conduct? ☑︎ Yes flyteorg/flyte
