You have a mistake in some of your custom PHP files. It uses non existing interface "Espo\Custom\Field\AddressFormatter".

Hi ctheuring,

You can share these files by providing their contents, and the community will try to figure out what needs to be changed in them for the upgrade to work.

I want to upgrade from 8.4.2 to 9.0.4 on a ubuntu-Server 22.04. with Apache2
All upgrades before run without problems.
The file AddressFormater.php is placed in .../Espo/Custom/Field/ and plus in (original) .../Espo/Custom/Field/Address/
The owner is www-data and the rights are set to 777 (so avoid problems).
I've defined a new Address-format 5 - runs well.
What's going on?

Christoph
