Research direction

Look at the deployment logic in the codebase, likely in a deployment manager or SQL execution module. The error 'fail to get tablet, table dbd.' suggests a missing table reference. Start by searching for where deployments are created and how they handle table dependencies. Run the provided deploy and curl commands to reproduce the issue, then trace through the code to see why the deployment succeeds but the call fails.
