could not retrieve QueryExecutor for channel %s, error %s

Error message

could not retrieve QueryExecutor for channel %s, error %s

What it means

getInstantiatedCC called stateFetcher.FetchState and failed to obtain a QueryExecutor for the channel — a VSCC execution (infrastructure) failure rather than a policy violation, often transient ledger access trouble during commit.

Solutions

1. Check ledger state DB connectivity/health
2. Retry validation; the query executor may be temporarily unavailable
