Errors in Checkout for Some Users: Redirect URI Mismatch

[mcanaleta]

Hi everyone,

I'm sharing an issue we've been experiencing for a few days. Our Hydrogen store at https://outlet-pc.com/ has been running smoothly for several months, but now some users are reporting that they cannot complete the checkout. They encounter a "redirect_uri mismatch" error.

From their descriptions, the error seems to occur when they click the checkout button, which is a link to the checkout URL, to which we append the parameter "logged_in=true" if they are logged in. Clearing the cache appears to resolve the issue. I've attached a screenshot.

Thanks,

Did you update to the latest version hydrogen?

No, it was an issue on the Shopify side. It was only affecting Shop Pay authenticated users when using the logged_in parameter.

Initially, we did a workaround by disabling the logged_in parameter; although this affected the user experience, users could at least complete the checkout.

Finally, Shopify fixed the issue, and it is working correctly again now.

Thanks.
