Uncaught TypeError: Cannot convert undefined or null to object
I'm not sure this is a bug, but when I try to bind to property, the error I get is displayed. I have no idea why bind works with one document but not with the entire collection. Because the problem only affects the binding of the entire collection.

Error Message:

you probably need to use firebase 7. See #940
