failed to obtain information for Channel %s

Error message

failed to obtain information for Channel %s

What it means

Returned by SupportImpl.GetLedgerHeight when the peer has no ledger for the requested channel (Peer.GetLedger returns nil). It fires before any blockchain-info query — the channel is simply not joined/known to this peer.

Solutions

1. Check the wrapped error for the underlying ledger store failure
2. Verify the channel ledger is not under rebuild/reset
3. Retry after the ledger store recovers
