Hey < Rachel Funk> is your flow simple enough to share

Rachel Funk · Answer

Unfortunately not it s ~450 lines

Rachel Funk · Answer

but I was looking in github at new changes we rolled out and noticed this

Rachel Funk · Answer

Would having a newline at end of file break my flow

Rachel Funk · Answer

this is one of two changes we just rolled out before this issue presented Otherwise nothing else has changed on our end

Kevin Kho · Answer

No it probably won t What Storage are you using and RunConfig

Zach Schumacher · Answer

are you using a k8s run and trying to use a path for your job template I got that error when my path was incorrect or the flow didn t have access to the path

Rachel Funk · Answer

apologies for the delay I forget to check this slack Storage = Local RunConfig = I think Dask Executor but we actually don t have RunConfig set up in our scripts as I see it <https docs prefect io orchestration flow config run configs html labels|outlined here> I think because the flows were set up over a year ago May that also be contributing to this issue We haven t had any issue before the last few days but I m not sure if your team s recent release may have broke something in our setup
