I've had no problem running upgrades in the past but when trying to run the upgrade from 7.1.4 to 7.1.5I get an "Argument 1 passed to Espo\Core\Exceptions\Error::__construct() must be of the type string, null given, called in /home/public/application/Espo/Core/Console/Commands/Upgrade.php on line 373.
I've looked at the code but there's nothing obvious (to me) - just that it's failing with blank error string as far as I can tell.
One thing I'd previously discovered (with the excellent assistance of my web host Hostek!) is the memory limit on upgrading. They recommended using php -d memory_limit=512M command.php upgrade which enabled previously failing upgrades to proceed. Hope that little fact may help others.
