Reproducible by going to

https://www.netlogoweb.org/web?https://m4a-gae.appspot.com/p/SJKz6u-2ciF8Za5hYlWI4f.nlogo

And entering in the command center:

random-seed 1

Click setup
Click go
At tick 275 I get

agent.getCoords is not a function

Note that the executable has a more reasonable error (though it provides no help localising the bad code):

DISTANCE expected input to be an agent but got the number 0 instead.

org.nlogo.nvm.ArgumentTypeException: DISTANCE expected input to be an agent but got the number 0 instead.
