hansenc opened a new issue #7732: URL: https://github.com/apache/pulsar/issues/7732
**Describe the bug** When I create a function (standalone, Java runtime) and start producing to the function's input topic, I can see that an instance of the function is created in the logs, but the function seems to never be called. Weirdly, if I trigger the function before producing to the input topic, the function is called as expected. I've created a (somewhat) minimal [test project](https://github.com/hansenc/pulsar-scratch) to reproduce this issue. I suspect user error, but I can't figure out what I'm doing wrong. **To Reproduce** Steps to reproduce the behavior: 1. Clone the test project [here](https://github.com/hansenc/pulsar-scratch) 2. `mvn clean package` 3. Run `com.github.hansenc.pulsar.FunctionIT` (from an IDE or otherwise) 4. Notice that `testWithTrigger()` passes while `testWithoutTrigger()` hangs, with the only difference being a call to `pulsar-admin functions trigger...` **Expected behavior** I expect the function to be called as messages show up in its input topic without needing to 'trigger' it first. **Desktop (please complete the following information):** - OS: macOS **Additional context** I've tried this with Pulsar version 2.6.0 and 2.5.2 with the same result. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
