Hi zuuuuk,
Please try modify .adef file of your project with below:

Option 1, disable sandbox:

sandboxed: false

For more info: Application Definition .adef - Legato Docs

Option 2, mount the file for Legato app:

requires:
{
file:
{
/home/root/tt /home/root/tt
}
}

For more info: Application Definition .adef - Legato Docs

Then rebuild and try again.

Hope it helps.
Thx
