@lcnr @BoxyUwU It's hard to tell due to the rollup which PR is responsible but I am guessing one of you might want to take a look at this.

[apiraino]

I see a number of issues with this error and they point to #105009. I'd close this as duplicate, makes sense?

(as per other bisections, the PR responsible could be #104411)

[apiraino]

Closing in favor or #105009
