Describe the Scenario

Hello,

I always get an error when updating Bookstack. What do I need to do to fix this error?

In Factory.php line 730:
The HOME or COMPOSER_HOME environment variable must be set for composer to run correctly

However, the update runs normally.

Or can I ignore this message?

Best regards Matthias

Exact BookStack Version
