[ppebb]

Using osv with vimspector, adapter configuration:

{
    "$schema": "https://puremourning.github.io/vimspector/schema/vimspector.schema.json#",
    "adapters": {
        "nlua": {
            "host": "127.0.0.1",
            "port": "8086"
        }
    },

    "configurations": {
        "osv": {
            "adapter": "nlua",
            "configuration": {
                "request": "attach"
            }
        }
    }
}

Vimspector errors, and gives the logs

In the last line, 'stackFrames': [], the second one, {'id': 2, 'name': 'main'} is missing the line field, which is required in a StackFrame

That's slightly intriguing why the source is not found, but it should now return 0 to be more in line with the spec. Thanks for precisely pointing it out!
