    Check your AL files, you have for sure an object with the same name.

    Check all of AL files and make sure the page name is unique.

    Check if your app has dependencies with other app. Maybe it is already declared in the other app.

    Manikanta_501 isn't talking nonsense. Probably, the code compiles fine but still gives you the errors?

    Are you maybe using an UNC path to store your VS code folders? If so, try copying the solution locally or mapping a network drive.

    Even though this question was asked quite while ago...

    I ran into this as well. My project contained only one file and a workspace file looking like this:

    .."folders": [
            {
                "path": "APP/src",
                "name": "App"
            },
            {
                "path": "TEST/src",
                "name": "TestApp"
            },
            {
                "path": ".",
                "name": "root"
            }
        ]...

    Absolutely no reason for this error was given. Somehow VS Code stumbles here. After deleting the App-Part in my workspace file, this issue was solved for me.

    So I end up with:

    "folders": [
            {
                "path": "TEST/src",
                "name": "TestApp"
            },
            {
                "path": ".",
                "name": "root"
            }
        ]
