I’ve a problem when coming back from sleep mode in iOS when project is loading. The script playcanvas-stable.min display this error.
To reproduce it you have to press the sleep button while loading a play canvas project and then coming back. The heavier the project the more it will happen.
My guess is in this case success() called for 206 (partial file). If I understand it right, the function can be called even if the JSON downloaded is not complete.
The perfect solution for us would be to call _onError() when this happen. And have a way to subscribe to the error so developers could do what they want to handle it.
