I get an issue when running Proguard. Attached log:

HI @jacob-lerenius ! Can you provide a reproducing sample?

jacob-lerenius commented 3 weeks ago

Unfortunately I'm not allowed to upload the project. I thought it may be some way to handle if the index is -1 anyways. I can help testing a possible solution if it helps. Sorry

mrjameshamilton commented 3 weeks ago

Unfortunately without a reproducing sample it's not obvious what the issue is. Handling the -1 case in that location would be handling a symptom of the problem rather than fixing the cause.
