What’d cause this error? I’m using an eagerly loaded template now (that’s in the project tree) as opposed to an S3 file path for the `job_template_path`  now. Same template loaded via S3 during flow init didn’t throw this error, but registration blows up with this error now.

I still owe you your pdm issue I haven’t forgotten. Will write that today. This one is pretty weird. Would you be able to share the RunConfig?

kinda surprised it didn’t emit an error from my code though and instead just blew up library code
