如何在VS Code中将布尔参数传递给delve？

I am trying to pass argument to delve through VS Code but it doesn't work.

This is how to pass argument to a go program through delve:

dlv debug github.com/docker/swarm -- create

I tried many different solution in my launch.json:

"args": [
    "--",
    "create"
]

"args": [
    "--create"
]

"args": [
    "create"
]

After many attempts, I found the right one:

"args": [
    "--create",
    "true"
]
