Recommendation

The docs indicates a maximum string length of 80 for reference parameter. When reference length is replaced with a shorter string, GrabPay Drop-in works as expected.

Current Behavior:

Selecting GrabPay Drop-in option on GitPod instance returns a 422 error with message: "reference='Reference 0e852a1a-f187-49e9-9092-221772cbd46c' given is invalid.

Expected Behavior:

Selecting GrabPay Drop-in option on GitPod instance should redirect user to weblogin.grab.com to authenticate user and continue with checkout flow.

Steps To Reproduce:

1. Create test merchant account on Customer Area
2. Add GrabPay_SG payment method to test merchant account
3. Open ./app/main/sessions.py file
4. Change request['amount'] = {"value": "10000", "currency": "EUR"} to request['amount'] = {"value": "10000", "currency": "SGD"}
5. Change request['countryCode'] = "NL" to request['countryCode'] = "SG"
6. Run ./start.sh on GitPod instance
7. Visit the URL generated by GitPod instance
8. Click on Drop-in
9. Select GrabPay as the payment method you want to check out with

@shauncAdyen Thanks for creating the issue. I can replicate the problem (thanks to all the details and info in your issue), I will try now to upgrade the Drop-in to the latest version as the first step. I will keep you posted. Thanks
