Describe the bug

Hi there, gatus is throwing the following error when I access its web ui:
panic: unknown encoder level

goroutine 104 [running]:

Not sure from which version it started happening, as I did not updated it for some time and few newest still does not work, reverting to v5.0.0 makes the web ui work again.

Of course, the monitoring still works, it is just the UI.
