Missing properties are not reported clearly

[tgdavies]

I had a reference to a property in my state.yaml:

replication: ${my_data_default_replication}

which I had failed to define in my props file.

The exception message is not very helpful.

@tgdavies Which version of kafka-gitops are you using?

The string "reading props from" doesn't appear in its sources anywhere. 🤔

ParserService.java:84 is about extracting the exception root cause and unfortunately offers quite some opportunities to fail with a NullPointerException:
https://github.com/devshawn/kafka-gitops/blob/0.2.15/src/main/java/com/devshawn/kafka/gitops/service/ParserService.java#L84

Would you be able to share your desired state file, the properties file, and the exact command you're running?
