 Just tried to work with WP version 5.0 beta 2 in one of my personal
 project. When I tried to edit a custom post I notice that one of my custom
 taxonomy (Name: lang, Title: Language) not working. Neither showing old
 terms nor able to create new!

 When I clicked on "Add new term" in the Language taxonomy box, shows me
 "The editor has encountered an unexpected error." with three buttons. I
 have added the screenshot.

 When I click the "Copy Error" button and paste it on a text editor, it
 shows:
