chunk %s not found: %w

Error message

chunk %s not found: %w

What it means

Chunk authorization lookup failed: GetChunkByIDOnly returned an error or an empty result (inner 'empty result' sentinel if nil,nil), so the chunk cannot be resolved for scope checks and access is denied with a not-found error.

Solutions

1. Confirm the chunk ID exists
2. Check chunk service/storage health for the inner error
3. Handle uniformly as not-found to avoid leaking existence
