Error caused by lerna.json without "packages"

[jeffrson]

I don't know how it behaved in the past, but nowadays "lerna.json" without "packages" is perfectly valid - IMO with both lerna and lerna-lite.

When there is a lerna.json, created by lerna init (lerna-lite or lerna), as simple as

{
  "$schema": "node_modules/@lerna-lite/cli/schemas/lerna-schema.json",
  "version": "0.0.0"
}

> ultra --info

only shows this error message

error Cannot read properties of undefined (reading 'length')

However, with

{
  "$schema": "node_modules/lerna/schemas/lerna-schema.json",
  "packages": [ "packages/*" ],
  "version": "0.0.0"
}

it works:
