Description
I get a CORS error (preflight OPTIONS request fails) when I try to use the library from a frontend app.
I created a minimal setup project here https://github.com/makmonty/ra-bug-min-rep
Note: I don't get the error if I do the same requests with my own implementation as such:
const result = await fetch('https://retroachievements.org/API/API_GetGame.php?y=<webApiKey>&z=<username>&i=<gameId>')
const data = await result.json()
So it's not a configuration issue at the API side.
My environment is:
Browser: Firefox 131.0
SO: Arch Linux

Research direction
Start with the linked minimal setup project and reproduce the failed preflight OPTIONS request in Firefox. Compare the library request with the direct fetch example in the issue, then trace the library entry point used by the frontend. Done means the frontend can make the same request without a CORS preflight failure.
