Attempted to load class "JFactory" from the global namespace. Did you forget a "use" statement?

Attempting to use the cv command on a Joomla 5 installation. I'm calling the command as follows using the www-data user:

`$ cv api job.execute --user=cronuser cwd=/var/www/joomla
`
and receiving the following error:

```

In Joomla.php line 651:

Attempted to load class "JFactory" from the global namespace.
Did you forget a "use" statement?
```

Please advise, as this is putting a hold on the implementation.

Thank you

Start by reproducing `cv api job.execute --user=cronuser cwd=/var/www/joomla` on Joomla 5 and inspect Joomla.php at line 651, where the reported JFactory error occurs. Determine the compatibility change needed and verify that the command completes without the global-namespace error.
