Cannot set arguments for go app during debugging - go

Question

I'm trying to debug my goland app and have some problems with launch.json file. My app should be run with argument: my_go_app -c path_to_config.
My launch.json looks like:
{
// Use IntelliSense to learn about possible attributes.
// Hover to view descriptions of existing attributes.
// For more information, visit: https://go.microsoft.com/fwlink/?linkid=830387
"version": "0.2.0",
"configurations": [
{
"name": "Launch my go app",
"type": "go",
"request": "launch",
"mode": "auto",
"program": "${fileDirname}",
"args": ["-c /home/roman/projects/myapp/some.json"]
}
]
}
But when I debug app I have received the following error:
flag provided but not defined: -c /home/roman/projects/myapp/some.json
Usage of /tmp/__debug_bin542579318:
-c string
Specify the configuration file. (default "config.json")
Without debugging my app runs with success. Please explain what is wrong...
