Something went wrong Please try again later when moving ticket in roadmap

Currently when you move a ticket in the roadmap to another date, Jira is showing the error 

 

Something went wrong

Please try again later.

I tried to move the epic including the tickets to todays date. 

In case this is not possible, what is the easiest and fastest way to adjust all tickets that are in this epic?
