Issue with Red Error Pop-up in Microsoft Teams Tab Application

Nivedipa-MSFT, 
I've been encountering the AppInitTimeout error each time I see this error pop-up. Below are the console logs that may help identify the issue. Despite adding a local page from within the application, I still encounter the AppInitTimeout error. 

This is a simple tab application created using Visual Studio. I created a Razor page called test: 

@page "/test"

<h3>Hiiiiiiiiiiiiiiii</h3>

@code {

}

I then updated the manifest to point both the contentUrl and websiteUrl to the test page as follows: 

"staticTabs": [
    {
        "entityId": "index",
        "name": "Home",
        "contentUrl": "${{TAB_ENDPOINT}}/test",
        "websiteUrl": "${{TAB_ENDPOINT}}/test",
        "scopes": [
            "personal",
            "groupChat",
            "team"
        ]
    }
],

However, I still keep getting the error pop-up.
