Developing an offsite payment app

Hi, I am developing an offsite payment, I am following the Shopify documentation to develop the app. With so much struggle I was able to complete the steps and install the app and bring to the checkout page.

Now I am facing an issue on the next step. So When I select my payment app as payment provider and click the pay now button. I am not getting redirected to a my payment portal and getting this error “There was an issue processing your payment. Try again or use a different payment method.”

can some one help me debug/fix this issue?

Hello Ginthu, have you found a solution or resolved the issue? I’m also working on developing an app and following the same documentation.
