Read the error message and the page it links to.

Since onEvent() is no longer supported, might you want to fixed the default startup_scripts/script.js.
I did not write the script.js as it installed with the mod and it would therefore seem to be a bug.

This is the generated startup script, changed... about three months ago. Did you copy over your script folder from another pack perhaps? Because you should not be getting onEvent based scripts at all anymore

My bad. I forgot some code from my git repo had prevented the new defaults. Thank you for your patience with my error.
