Current behaviour

In the scrum backlog of a company-managed Jira Software if a user without the Edit Issues project permission tries to drag and drop an issue into a sprint, they will see the following generic and misleading error message:
 

Something's gone wrong
Refresh the page and try again.

In the network response you will see the true error:

{"errorMessages":["You do not have permission to edit this issue."],"errors":{}}

Desired behaviour

Make the UI error more informative, use the text of the network response instead.
