Visual Studio Code not working Golang debugging (WSL Ubuntu)?

Question

go

Hello, I have a problem with the Golang debugger in Visual Studio Code.
Set up environment variable:

export GOPATH=$HOME/go
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin

Installed dlv and 10 more tools offered by Visual Studio Code.
I registered the launch.json configuration:

"configurations": [
        {
            "name": "Launch",
            "type": "go",
            "request": "launch",
            "mode": "debug",
            "program": "${workspaceRoot}",
            "port": 2345,
            "host": "127.0.0.1",
            "env": {},
            "args": []
        }
    ]

I set a breakpoint, start the debugger, it starts, writes to the Debug Console:
API server listening at: 127.0.0.1:2345
and that's it! Nothing else happens.
Thank you in advance!
