"Uncaught TypeError: Cannot read properties of undefined (reading 'steps')"

I loaded a Sokoban game in griddly.ai and modified the rules a bit. I pressed "play" though I think the button was inactive. Nothing happened, but I got this in the error log:

HumanPlayerScene.js:594 Uncaught TypeError: Cannot read properties of undefined (reading 'steps')

I cut off the traceback because it's long and repititive, find the full traceback in the log: https://gist.github.com/cool-RR/97a4d6043ef2c63fd119619dbb5ac568

Thanks for this bug report! Its easy to reproduce so good catch :D

I'm currently in the process of separating the GriddlyJS components into NPM modules which can be used anywhere... These will be in a separate repository so I can track the bugs better.

Hmm, my two cents (with much less background than you about this project) is that it'll be better to keep them in the same repo. Modularity is less important than the dependency hell you could get yourself into by separating to two repos. But let's discuss that in video.
