flowchartsman opened a new issue, #20020: URL: https://github.com/apache/pulsar/issues/20020
### Search before asking - [X] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Version issuing a `pulsar-admin functions stats` check on a go function will cause it to crash if no user metrics are defined. This is because it makes a similar assumption to the other metrics calls that the result of `gi.getFilteredMetricFamilies` will have a `len` of at least 1. If there are no user metrics, it will not, and it will cause the agent to restart. PR incoming ### Minimal reproduce step 1. create go function w/o user metrics 2. `pulsar-admin functions stats --fqfn tenant/namespace/functionname` 3. function will crash/restart ### What did you expect to see? Actual stats ### What did you see instead? stats of zero. function restart ### Anything else? _No response_ ### Are you willing to submit a PR? - [X] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
