Getting 'Method Not Allowed 405' Error – How Do I Fix This? or Why Am I Seeing a 'Method Not Allowed

Thanks for all the tips, folks!

Turns out it *was* a CORS issue—my backend wasn’t allowing POST. Added the right headers and it’s working now.

Weird thing is, it was fine locally but broke in prod. Gotta love deployment quirks, right?

Appreciate the help!
