Plugin suddenly stopped displaying reviews

Recently the API key I was using stopped working, so I created a new key and got that working with the plugin.

I was able to successfully pull the reviews using my API key and Place ID, but for some reason, the reviews are not showing on the front end of my website.

And I am receiving this error in the console:

Uncaught TypeError: Cannot read property 'length' of null
