Debug Traefik/Yaegi Plugins in Devcontainers

Question

I am currently developing a plugin for Traefik 2 that gets intepreted by yaegi. I am unable to debug tokenValidate.go because I receive this error message when I start the debugger.

Based on the plugin documentation I have implemented the handler (code snippet)

func New(_ context.Context, next http.Handler, config *Config, _ string) (http.Handler, error) {

    tokenValidatePlugin := &TokenValidatePlugin{
        keys: make(map[string]interface{})
    }

   return tokenValidatePlugin
}

Current launch.json config

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch file",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "program": "${file}"
        }
    ]
}
