Hi there, what's the details of the error?

[vale acorn]

This is the error.

Actually i have a button and when i click on button i want to open the checkout page

[runic halo]

Ok, basically in your button click handler, you create a request to your backend and the backend responds with a 30x redirect response code, am I right?

[vale acorn]

Yes, in backend i have created a api and inside api i am using stripe.checkout.sessions.crete

[runic halo]

OK, the easiest way to fix this problem is using a form submission. -> Create a form and put your button inside, set the form's action to your backend endpoint that create a checkout session

[vale acorn]

Okay but on button click why is not working.

[runic halo]

It's a limitation of browser implementation.

[vale acorn]

Okay.

So basically without form action we can't use it right?

[runic halo]

There's another way.

Instead of redirecting (i.e., 30x response code), your backend can respond a 200 to your frontend, where you need to call window.href.location=CHECKOUT_URL to manually redirect to the checkout page.

[vale acorn]

Okay, yes when i try to return res as 303, i am getting error as api key is not defined.
Now i do as you say

[runic halo]

Check your code and see if the API key is set properly.

[vale acorn]

Yes i have set the api key

[runic halo]

How about your backend code?

[vale acorn]

This is the backend code

[runic halo]

Can you check if the values are set in the .env file?

[vale acorn]

Yes values are set

[runic halo]

OK, can you share with me the full error message?

[vale acorn]

This is showing in console.

[runic halo]

Where do you see this error? in your own page or checkout page?

[vale acorn]

In my own page.

Can do you know which line of your code cause the error?
