unable to delete items from Cart in Shopping App in SAP Build Apps

[Bharath369]

Hi,

I am follwing the tutorials 7 - Trigger Process from Your App: STEP 6 , and when I click on Purchase, it is giving me the below pop-up. I am unable to delete some items in the cart. The Delete icon functionality is not working. I am not sure if I missed any thing during during the build. Can you please help me on how to delete the last two items from the cart?

Thanks,

Bharath

It is tough to diagnose without seeing more of the project (I wish we could just add a project file to a question).

Purchase Issue

The message comes about when you are sending input parameters of the wrong type. If you use developer tools, you can see the data that is being passed and make sure this confirms with the process requirements.

You can see the proper JSON in the Control Tower > Environments > Triggers

Delete issue

Tough to know if I do not see ... what message are you getting? What is your logic? I would think that perhaps the wrong ID is being sent to the CAP service, but it depends on what the nature of the error is.
