Exercise 6: logs files are empty

[Oqulent]

OS: Ubuntu server 20.04
Cardano-node version: 1.13.0
Node runs in Tmux.

The exercise 6 has a section where we set up logging to be saved in a file as follows:

"setupScribes": [
{
"scFormat": "ScText",
"scKind": "StdoutSK",
"scName": "stdout",
"scRotation": null
},
{
"scFormat": "ScText",
"scKind": "FileSK",
"scName": "logs/mainnet.log"
}
]

This setup, used in conjunction with LiveView, creates log files that are empty.
