Troubleshooting global null pointer exception

Processing

Thanks micuat. On running the program it fails immediately with this error message, and the canvas window does not appear.

I tried using processing-java (and reinstalled it now as github suggests. I am on macOS 10.15.7) but while it can run the program (and get the same error) the --output DIR option results in no files being written in DIR :slight_smile:
