I have uploaded a new version that removes those two calls - GMS2 version upload process in unnecessarily convoluted - since GMS2 does not actually have any extension export mechanism at all, you have to submit your extension update to marketplace and then download the extension file from your marketplace page. Trying to do this too quickly can result in oddities like these - in debug version I have it dump HTTP requests and compilation error stack trace into output log using a custom script called "trace" (which just converts arguments to strings and calls show_debug_message), and that version ended up being included instead of a release build that I had finished compiling seconds before starting submission.
