LeBW opened a new issue #1453:
URL: https://github.com/apache/incubator-inlong/issues/1453
<!--
Thanks for contributing to InLong!
Please explain your issue precisely, and if possible provide a reproducer
snippet (this helps resolve issues much quicker).
-->
#### Expected behavior
agent should send message to dataproxy when detect change.
#### Actual behavior
the agent and the dataproxy fails to communicate.
#### Steps to reproduce
1. deploy inlong using `docker-compose`
2. new a business in `inlong-web`.
3. create `.inlong` dir in agent and `bid.local` to indicate dataproxy
address.
4. send a HTTP request to the agent to add a trigger.
5. add a line in the target file in the agent.
6. then we can see the error in `agent` and `dataproxy`.
Here is the error in agent
```
