Tracking error EAUTH502

[mboy1011]

Hi, Cattr App Team!

I've encountered an issue in regards to:

Unhandled system error occurred: Error: Cannot assign null to property App\Rules\TimeIntervalDoesNotExist::$user of type App\Models\User

Backend traceId: 928fda4f-392d-4b2e-91fe-b563c5ad9f04

Client traceId: 9d8e4224-7c97-4d45-983d-79550ac40811

See image below for proof.

I have a server running on:
Linux cattr 6.8.0-79-generic #79-Ubuntu SMP PREEMPT_DYNAMIC Tue Aug 12 14:42:46 UTC 2025 x86_64 x86_64 x86_64 GNU/Linux

I'm currently on a Docker instance using the default docker-compose.yml:
registry.git.amazingcat.net/cattr/core/app main 534858b9bce6 7 months ago 244MB

Here's the error from the backend using docker-compose logs:

[2025-09-02 08:34:33] production.ERROR: Cannot assign null to property App\Rules\TimeIntervalDoesNotExist::$user of type App\Models\User {"userId":2,"trace_id":"928fda4f-392d-4b2e-91fe-b563c5ad9f04","request_uri":"/api/time-intervals/create","request_content":[],"exception":"[object] (TypeError(code: 0): Cannot assign null to property App\\Rules\\TimeIntervalDoesNotExist::$user of type App\\Models\\User at /app/app/Rules/TimeIntervalDoesNotExist.php:38)

When I checked the time_interval table from the database, it seems it's empty when a regular user but when I use the Admin it has 1 rows of data but still the error occurs and couldn't automatically synced up to the server.

I've tried to install on different machine, Windows 11 & Windows 10 still no luck. I tried to change the Settings from each user seems no luck.
