that just means you're doing the redirect incorrectly

can you share

• the backend code that creates the CheckoutSession and returns information to the frontend
• the frontend code that calls the backend and tries to do the redirect

so I can have a look?

I don't have it readily available. I'd have to check back in with you later. Any general advice on what to look for & then correct on my end?

yep

so usually this happens because your backend tries to do a 303 redirect return

but your frontend is calling the backend function through a XMLHttpRequest/Fetch/Ajax etc

which doesn't work, you can't redirect from an XMLHttpRequest.

so instead you should either

• change the backend to return a 200 with some response body(like a JSON object that contains the the url field of the CheckoutSession) and on the frontend, extract that and set window.location = response.url for example to do the redirect that way
• change the frontend so you call the backend from e.g. a <form action="create-checkout-session"> instead of a XHR.
