Hello,
Sorry to bother everyone again. A few days ago I posted a similar issue — after upgrading EspoCRM, the list view pages stopped working properly. At that time, I reverted the system files to the version before the upgrade, and the error disappeared.
However, today I upgraded the system again (currently on version 9.1.5), and I encountered the same issue.
Specifically, the User list view fails to load properly, and I found the following error in the console:
This occurs in list.js or espo-main.js when rendering the collection.
I did not modify any core files or custom views under the Users module. The issue appears immediately after the upgrade.
Has anything changed recently in ListView or data collection structure that might affect this?
Any hints or guidance on how to fix or debug this would be greatly appreciated. Thank you!
