List of steps to reproduce:
- Check your global.js on Meta. Either add console.log('global.js'); there or identify some code there that has a discernable effect on wiki pages (you will need it to verify that global user JS has loaded).
- Go to https://en.wikipedia.org/wiki/Test?debug=1 (or any wiki other page with ?debug=1 in the URL).
- Check that your global user JS has loaded.
What happens?:
Global user JS does not load.
What should have happened instead?:
Global user JS should indeed load.
Details:
I checked it in Chrome, @SerDIDG, who found this bug, checked it in Firefox. I looked at the requests in DevTools, and I saw a request to https://meta.wikimedia.org/w/load.php?debug=1&lang=en&modules=ext.globalCssJs.user&skin=vector&user=Jack+who+built+the+house&version=1tm4h which is supposed to fetch the global.js. But the response was:
mw.loader.implement( "ext.globalCssJs.user@96o4l", [
"/w/load.php?debug=1\u0026lang=en\u0026modules=ext.globalCssJs.user\u0026only=scripts\u0026skin=vector\u0026user=Jack+who+built+the+house\u0026version=1tm4h"
] );No data.
On the other hand, if I remove debug=1& from the URL, the response is correct, see https://meta.wikimedia.org/w/load.php?lang=en&modules=ext.globalCssJs.user&skin=vector&user=Jack+who+built+the+house&version=1tm4h.
