This scenario is using RSO code in it by copy/paste. Since mod works without problems my guess would be that it has been somehow modified or contains obsolete version of code.
I do hope that there is an information attached to scenario that it uses RSO and description of changes made to it to comply with mod license.

The scenario script is calling math.random() and not using the result - which is a pointless operation because calling it doesn't do anything if you don't use the result.

I changed the mod API so in 0.16 and later specific API functions that are only useful if you use the return result will error if the game detects that the result is going unused.

Like calling surface.find_entities_filtered() and then doing nothing with the found entities - it's dead code.
