That's the thing, I have no idea what BuyNow is. I searched all throughout my code and it does not exist. On the github you can see other developers, with completely different projects seeing the same exact logs, as if something has been injected.

My code from today was the exact same as it was last week. So it seems like some package or dependency has been compromised perhaps?

Edit: And when I tried to search for it, I could not find a single post anywhere on the web about it.

There was a "Buy Now Pay Later" feature thing that Edge was pushing at the tail end of 2021 that was available in developer channels which might be related

Ah, I see. So you did not write the file you posted.
