If a log contains a null\n or null, the Vue app on the logging page will fail. This results in an endless loading spinner and no error message.
To fix this, the PHP backend should filter these "logs" out.

Steps to reproduce¶

1. Add the buggy.log.json into the logfiles directory
2. Try to open the corresponding logs in the Gambio Admin
3. You should see a loading spinner endlessly spinning

How it should be¶

The loading spinner should vanish after a while and you should see some (or no) logs.

Note¶
