Google Pay Integration Issue in .NET MAUI Blazor Project

I am integrating Google Pay with my .NET 8 MAUI Blazor project, but I'm encountering issues. The JavaScript code works fine in a regular website project, allowing me to pay and debug using a "TEST" environment.

On Android, the app crashes, and I receive the following error:

Java.Lang.NullPointerException: Message=uriString

using Windows Machine, the app opens the GooglePay website in the browser, but I encounter the following error:

Something went wrongTo make this purchase using Google Pay, open this website in a browser app, such as Chrome or Safari. [OR_BIBED_15]

This is the JavaScript code

I followed Google's tutorial and integrated the necessary JS code, and the script works as expected in a regular website project.

I expect the Google Pay integration to work within my .NET MAUI Blazor app, similar to how it functions in a regular website project.
