When I try to use it, it keeps saying "Unknown checkpoint syncer type".

I see that although rust/hyperlane-base/src/settings/checkpoint_syncer.rs seems to be designed to support GCS for storage, but rust/agents/validator/src/settings.rs doesn't have it and only expects either localStorage or s3.

Is it still WIP to support Google Cloud? Or how do you specify the Checkpoint Syncer settings to use GCS bucket for storage?

hi @sapph1re, yes it seems like this feature has a bug where the validator can't be configured. See this issue for more details, although I don't really have the bandwidth to support with the fix now
