Theme causes Safe Mode in 2022.8.0b0

Using the Metrology theme caused HA to go into safe mode when upgrading to 2022.8.0b0.

This was initially reported as a Core issue but was determined to be a theme issue. Core issue with information about what is triggering this is here: https://github.com/home-assistant/core/issues/75847

There's a code typo as pointed out by @frenck. Thanks for testing it and letting me know. I'll push a new fix.

[Madelena]

May I ask how you downloaded the theme?

I just downloaded the 1.6.2 prerelease and checked, but the buggy lines that @frenck pointed out had already been removed:

[frenck]

It's on the main branch (right now).

[Madelena]

Should be fine now that the code for the bug fixes has merged with the main branch.

When this issue occurred, I had the theme manually installed from the main branch. I've now switched over to using HACS to install this. I've installed version 1.6.2 via HACS and restarted Core successfully without issue. Thanks!

@iridris Awesome! I'm glad the bug is fixed. Thanks for testing this. :)
