How to pass command-line arguments in debug mode in VSCode with golang

I am having difficulty in passing command-line arguments in VSCode (debug mode) with golang.

Below is the small code example and the launch.json:

package main

import (
    "flag"
    "fmt"
)

func main() {
    flag1Ptr := flag.Bool("flag1", false, "flag1 is a flag")
    flag.Parse()
    fmt.Println(*flag1Ptr)
    fmt.Println("Hello, world")
}

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${fileDirname}",
            "env": {},
            "args": [
                "-flag1"
            ]
        }
    ]
}

The output is always "false" for *flag1Ptr but it should be "true".

Update: The issue disappeared after closing down VSCode and reopening it (I am on a Mac(osX))

For me just adding launch.json to .vscode worked but not with Run Current File or Node.js options in RUN AND DEBUG menu, I needed to use Launch Program and it worked

View -> Run -> RUN AND DEBUG -> Launch Program

list all params, for example, command is:

"hello.exe -in InfoEntity.java -out aa.out"

the debug config is:

{
    "version": "0.2.0",
    "configurations": [
        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "auto",
            "program": "${fileDirname}",
            "env": {},
            "args": ["-in", "InfoEntity.java", "-out", "aa.out"]
        }
    ]
}
