Hi,
We were using Beam v2.23 and recently, we are testing upgrade to Beam v2.26.
For Beam v2.26, we are passing --experiments=use_deprecated_read and
--fasterCopy=true.
We run into this exception when we resume our pipeline:
Caused by: java.io.InvalidClassException:

It looks like it is not able to deserialize objects from our existing
checkpoints. Is there any way we could resume our v2.23 checkpoints by v2.26?
Thanks for any suggestions.
Antonio.
