To reproduce, try for example to call mmr_generateProof(11369888, 0x1cd750449e2169f16475b6cfc7ebfd48113bc4eace0aad288ebc137e403f65e3) for Rococo

The error that I'm getting locally is:

2024-07-19 21:29:44.475 ERROR tokio-runtime-worker runtime::mmr: [GenerateProof] MMR error: InconsistentStore

This error is triggered when an element is not found in the offchain storage.

I synced Rococo from scratch locally and it works as expected. Maybe the Rococ RPC nodes were synced from a snapshot and probably the snapshots don't include the offchain db data.

The DevOps team is resyncing the Rococo snapshots. It will take 2-3 days. Will get back with updates after

The Rococo snapshots were synced and now everything works correctly. Resolving.
