zarr.errors ArrayNotFoundError is gone in zarr 3.0

[thagusta]

Hello,

Simple problem, but I can't find documentation how to change my code from zarr 2 to 3.
the migration guide told me to make a new issue.

I have in my code:
from zarr.errors import ArrayNotFoundError

and use it in an try & except to catch if there is no zarr array.

What is the appropriate exception now?

hi @thagusta, sorry that the migration guide wasn't complete here. I don't think we have implemented a replacement for the ArrayNotFoundError, but I think we need to. At the moment, if you try to use open_array and the array doesn't exist, you will get a FileNotFoundError, but we should absolutely replace this behavior with ArrayNotFoundError.
