Debug not works with "Sam local start-api" with "--debug-port" and "--warm-containers"

With this command:
`sam local start-api --template-file template.yml --region eu-west-1 --debug-port 5555 --warm-containers EAGER`

and this launch.json
```
{
"name": "Attach to SAM CLI",
"type": "node",
"request": "attach",
"address": "localhost",
"port": 5555,
"localRoot": "${fileDirname}",
"remoteRoot": "/var/task",
"protocol": "inspector",
"stopOnEntry": false
}
```

my Visual Studio Code doesn't attach to container, I have no error or log, simply after 5 seconds the debug's topbar disappear.
The terminal logs doesn't show "Debugging listening on...." when I try lo execute an HTTP request.

All works fine removing --warm-containers param.
