Nostr Relay sync permission issue

I am trying to use the “Sync Public Relays” feature and encountering this error message:

EACCES: permission denied, open ‘./data/store.json’

I don’t see this file in the ~/umbrel/app-data/nostr-relay/data directory.

Suggestions on how to fix?

Update: I have solved this issue. It appears the problem was that I was using a custom user name, not “umbrel”, so the user didn’t have write permissions. I was able to fix it using this command:

sudo chown -R username:username ~/umbrel/app-data/nostr-relay/data
