Just using Collapsible throws an error as of recently #251

Have imported and used Collapsible like a month ago.
Worked fine then, but now it is throwing and error.

Error I am getting:
Invariant Violation: View config getter callback for component span must be a function (received undefined). Make sure to start component names with a capital letter.
(Not using a span anywhere, this came from a page where there is a View and a Collapsible)

Literally using Collapsible component in any of my pages throws this erron

Thanks for any help.
