Hello Flyters, I'm trying to think through the right way to handle what I think is some changed behavior in

FlyteDirectory

after version

1.4.2

. Our tasks/workflows create

dataclass

-based result objects, and we wrap these with a "FlyteResult" class that contains the result object as well as a

FlyteDirectory

. Some tasks may write files during execution, the

FlyteDirectory

is pointed at the folder containing these files, and these will automatically get downloaded (from e.g. s3) later by

FlyteDirectory::download()

when they are requested. However, some tasks don't write any files. The FlyteResult class that generically manages access to these things doesn't know which tasks do or don't write files, and always just calls

self.dir.download()

to get anything that might have been written (at the very least, a subfolder is written, but it may be empty). This worked fine in

flytekit 1.4.2

and previous, but starting with

1.5

, this raises an

Access Denied

, because the remote path doesn't exist. It seems that you actually have to write files during the task to get this remote folder to exist. It is not enough to create a subfolder under

current_context().working_directory

. One way to handle this is to check if the remote s3 "path" exists -- but I don't see how to do this with

FlyteDirectory

. At present I'm just creating a file with each task, to ensure the FlyteDirectory has something in it, such that the remote s3 path will be created, such that the call to

FlyteDirectory::download()

doesn't result in an Access Denied exception. This feels clunky. Better ideas?

the change from 1.4.2 to 1.5 was the move to fsspec. i assume this is a subsequent task you’re referring to? like a downstream task will always call download()?

Thanks @thankful-minister-83577, I'll give that a try and let you know.
