Klarna Payment – Post-Payment Error Message & OTP Not Prompted on Second Attempt

[shubhamvashist07]

Describe the bug
There are two issues occurring with Klarna payments:

After the user completes a Klarna payment, the payment screen shows an error message: "Safari cannot open the page because the address is invalid." even though the payment is successful. The user must manually close or cancel the screen.

During the first Klarna payment, the user is prompted for an OTP. However, for subsequent payments, Klarna does not ask for OTP, raising concerns about security and consistency in the authentication flow.

To Reproduce
Issue 1 – Invalid Address Error After Klarna Payment:

• Initiate a Klarna payment.
• Complete the payment process successfully.
• After redirection, observe the error: "Safari cannot open the page because the address is invalid."
• User must manually cancel the screen to return to the app.

Issue 2 – OTP Not Prompted on Second Klarna Payment:

• User initiates a Klarna payment for the first time.
• Klarna prompts for an OTP for authentication.
• On second Klarna payment attempt (same session or later), no OTP is prompted.
• Payment completes without additional authentication.

Expected behavior
After a successful Klarna payment, the user should be redirected back to the app without any error.

Klarna should consistently prompt for OTP to maintain a secure and consistent authentication flow, unless explicitly configured otherwise by Klarna.

I think you did not provide a valid return url that goes back to the app. Please double check that one

Let us try that. But what about the second issue "Issue 2 – OTP Not Prompted on Second Klarna Payment:"
