Research direction
Open Appy/Services/ClientNotificationsService.cs around line 85 and trace the FirstOrDefaultAsync result through later accesses to client. Confirm how the service handles a missing client, then ensure every downstream Contacts access is covered by the intended null-safe behavior. Done means the missing-client path returns a clean error instead of a NullReferenceException.

Description
Description
After fetching a client with FirstOrDefaultAsync, the code checks if (client == null) early, but later accesses client.Contacts without a null-coalescing guard, assuming the client is still valid.
Location
Appy/Services/ClientNotificationsService.cs(line ~85)
Risk
If the client is deleted between the null check and the property access (e.g. concurrent request), the code throws a NullReferenceException rather than returning a clean error.
Suggested Fix
Ensure the null check covers all downstream property accesses, or fetch the full object with required navigations in a single query with appropriate includes.
