[GitBox <gi...@apache.org>]

eolivelli opened a new issue #13358:
URL: https://github.com/apache/pulsar/issues/13358


   **Describe the bug**
   I have seen this NPE in FunctionStatsManager.reset.
   Probably it is a race while the function is still starting and it receives a "reset" request
   
   **To Reproduce**
   It is hard to reproduce it manually.
   
   **Expected behavior**
   No error
   
   **Screenshots**
   ```
