fly volumes list -a myapp-db to get the list of ids of volumes.
I got only one row with id: vol_2en7r1p2pg9rk5ab (I modified the last 3 characters) and when I run
fly volumes snapshots list vol_2en7r1p2pg9rk5ab I got this error:
Error: failed retrieving snapshots: failed to get volume vol_2en7r1p2pg9rk5ab snapshots: Type mismatch on variable $volumeId and argument volumeId (Int! / BigInt!)
What is the problem ?
