Ok, one more condition: the permission need not be granted. I can reproduce now.

Nico04 commented 10 months ago

Well maybe you need to refuse permission once. Because error happen after even if permission is granted (at least after one permission refusal) Thanks

After some basic test, I can confirm it doesn't throw anymore, thanks
