Image upload not working

[tostiheld]

Unfortunately, uploading an image is currently not working. Clicks on the "Select image" button don't seem to do anything. Upon further investigation, the following notice is show in the console:

Uncaught TypeError: Cannot read property 'id' of undefined

It seems the property 'post' of wp.media.model.settings is undefined, and therefore the 'id' property of said post. I got this from https://github.com/mennolui/wp-foyer/blob/master/raw/js/admin/foyer-admin-slide.js#L124

My wordpress version is 5.2.2
My Foyer version is 1.7.4
