This seems you set to wrong port.

[TonyKingdom]

You mean collector port?
The OAP server address was set via environment variables as describe in README.

SW_AGENT_COLLECTOR_BACKEND_SERVICES | The backend OAP server address | 127.0.0.1:11800

I double checked the key and value and it was absolutely correct.

I can't diagnose for your own env, but our e2e testing of nodejs agent is checking for every commit.
