${response.Error.Message}

Error message

${response.Error.Message}

What it means

The agent call succeeded at the transport level but the agent process returned a JSON-RPC-style error response; the driver surfaces the agent's own error message wrapped in a Go error. The actual cause is whatever the agent put in Error.Message, so this error text is dynamic.

Solutions

1. Read the wrapped Error.Message to identify the agent-side root cause and fix it there
2. Verify the agent process is the correct, compatible version and can reach the target database
3. Add logging around the call to capture the request id and full response for diagnosis

res, err := process.call(method, args); if err != nil { log.Printf("agent %s failed: %v", method, err); return fmt.Errorf("agent call %s: %w", method, err) }

When it happens

Trigger: Any agent RPC (e.g. 'shutdown' from close, warmup, benchmarkOneConnection, cleanupQueryPage, or ad-hoc calls) where the agent replies with response.Error != nil.

Common situations: The agent failed the requested operation (bad SQL, connection refused to the target database, internal panic); the agent binary is an incompatible version returning errors the harness does not expect; the agent could not authenticate to Kingbase.
