Hey there,

We recently got issues with getting into errors when reading files from Cloud Storage:

It also seems like there's a bug in the log output of the current retry.

Any idea why this can occur? It seems like intermittent issues but I want to make sure.

Thanks

Recently we have added new configuration properties to control reads from GCS, please use them to workaround any intermittent issues while reading from GCS.
