It's possible for the route to be null (no match) which leads to an
error like:
```
appwrite | [Error] Timestamp: 2023-08-30T21:39:58+00:00
appwrite | [Error] Type: Error
appwrite | [Error] Message: Call to a member function label() on null
appwrite | [Error] File: /usr/src/code/app/controllers/general.php
appwrite | [Error] Line: 50
```
This adds a null check to prevent the error.
