I have tried to update an Adapt AT server version 0.10.5 with framework version 5.18.4 to the lastest (version 5.20.1).

I changed to the "adapt_authoring" folder an ran "node upgrade".

But in the end the update failed.
This is the console output:

This script will update the Adapt authoring tool and/or Adapt Framework. Would you like to continue?
? Continue? Yes
? Update automatically? Yes

Software updates found.
