[GitHub] [apisix] GoneGo1ng opened a new issue #4375: request help: ‘v1/healthcheck’ returns an empty json
GoneGo1ng opened a new issue #4375:
URL: https://github.com/apache/apisix/issues/4375
### Issue description
The healthcheck is configured upstream and is already up and running, but calling the 'v1/healthcheck' interface does not return the expected result, instead returning an empty json.
One more question, I only created an upstream. Why does 'apisix/admin/upstreams' return a count of 2?
```
This is the service log, indicating that the health check is running normally.

I can't reproduce it. The only way to get an empty JSON at my side is when the upstream is not hit.
Maybe you can add more log to see what happened at https://github.com/apache/apisix/blob/405f69b3f9359b9200d595388d6dd6e3e6eb8248/apisix/control/v1.lua#L115
