I did some diagnosis in https://github.com/webcompat/web-bugs/issues/112923#issuecomment-1306044586 and looks like the site is getting unexpected results when trying to build a link for one of the network requests (due to group being a function, since array grouping proposal is enabled in Nightly):

/login/realms?group=function group() { [native code] }

Hello Yulia, adding a ni for visibility.

There is one more site affected by the proposal (https://github.com/webcompat/web-bugs/issues/112552), though this issue is more severe.

Thanks for the heads up. If you come across any others, can you add them here? https://github.com/tc39/proposal-array-grouping/issues/44 -- I will look into turning it off by default for nightly.

Oh, i see there is a label on webcompat -- https://github.com/webcompat/web-bugs/labels/type-array-grouping -- thats perfect. I'll track from there.

Array grouping is to be turned off by default in nightly from 1799619. This does not affect beta or release versions, as the proposal is not stage 4 yet. This can be closed when that bug lands.
