GCSFileSystem.exists() not working with bucket only

[yan-hic]

when checking on bucket existence, I get

ValueError: Bad Request: b/
Unknown project id: 0

Issue is actually with _list_buckets() and the get call to list buckets. The API requires the pass the project ID, not the project name - see https://cloud.google.com/storage/docs/json_api/v1/buckets/list and https://cloud.google.com/storage/docs/projects

BTW, that ID is also required to create a bucket so mkdir() has same issue

This was not spotted before if you happened to have project name = ID

I don't really know the difference between the "name" and "id" of a project, but if I instantiate GCSFileSystem with project= and what I thought was the name, then list, make and delete buckets works. This is then probably a case for better documentation and error messaging.

Thanks, @yiga2 , for listing your experiences with gcsfs, it's good to have more eyes on it.

Ah, in our case, the project name and id are the same :)

I was trying to find a way to look up a project ID based on client + project name but couldn't find any suitable API.
Google's gsutil and client libraries require project ID for a reason.
@martindurant to your point, maybe documentation should everywhere refer to project ID explicitly.
Feel free to close.
