Platform unknown instead of PSYCHOJS when syncing experiment to pavlovia / 404 not found

Here’s that error.

TypeError: Number.IsInteger is not a function

URL of experiment: WTK_Newstories [PsychoPy] Description of the problem: This error (TypeError: Number.IsInteger is not a function) comes up I can’t work out the cause of it. It begins at the first point after instructions, trying to draw basic text to a screen. It does not matter if the text comes from an input file or if I just type it in the box. It works fine in PsychoPy, using the automatic translation to JS. I have been trying to troubleshoot for a few hours now, and I am still stumpe…

Variable names to avoid are: class, core, final, image, index, Length, list, Object, Number, round, sound, Symbol, t, thisTrial, trials, util, visual.
