How to debug errors during install 8.1.2

I posted this some time ago but with other issues that were fixed. This error remains unsolveable after two weeks and I don’t know where to look for details on what failed. Any clues would be helpful.

sudo -u crm php74 ./bin/console suitecrm:app:upgrade -t "SuiteCRM-8.1.2"

And that completed the Installation but failed at the Legacy Post Upgrade:

Maybe there are some clues in logs?

  • install.log
  • suitecrm.log
  • php_errors.log
  • logs/ directory
