I found around 300 of these with query stacks all over the place 😅
not sure whats the best way of handling all these..
compiler-errors commentedon Jan 29, 2025
@matthiaskrgr: Could you share some other examples? There's no way to tell whether these are fixed the same way unless I see what reproduces those.
