I'm attempting to deploy an instance of FoundryVTT as a container on Cloud Run. I've set it up to mount a Cloud Storage bucket as a volume so that its data will persist when it restarts. The app launches fine when I've set it to use an in-memory volume, but obviously all that data disappears on a restart which I can't have between game sessions.
The error message:
