Cannot import and compile from VS Code

Hi,

I'm trying out VS Code with IRIS for Health 2023.2 (not available in above dropdown) in a local container.  I can open read-only files in the Objectscript viewer and have a local folder connected to the correct namespace.  However, when I make changes and try the "import and compile" option, I get:

ERROR #16006: Document <filepath> name is invalid

The first four chars of <filepath> appear to have been truncated

Here is my settings.json

{

    "security.workspace.trust.untrustedFiles": "open",

    "workbench.colorTheme": "InterSystems Default Dark",

    "intersystems.servers": {

        "local_docker": {

            "webServer": {

                "scheme": "http",

                "host": "localhost",

                "port": 9492

            },

            "username": "_system"

        },        

    }

}
