Error updating with update-varbase.sh

Problem/Motivation

On the latest update, my site returns from update-varbase.sh with an undefined varbase version?

[TypeError]                                                                                                                  
  Return value of "vardot\Composer\Commands\VersionCheckComposerCommand::execute()" must be of the type int, "null" returned.  

and then

varbase-refactor-composer <file> <drupal-path>

There was an error while preparing composer.json for Varbase updates. Please check /var/www/salsablanca.com/.update-error-log for more information.
If you are running Varbase 8.x-4.x or 8.x-5.x version, make sure to update varbase-project using the update command:
