Invalid date error occurred when editing Date Time picker field


When I choose a date from the date picker, Issue Editor raises an error saying that date format is invalid.


Set the Date Picker and Date Time Picker to match the format in Jira (System > Look and feel and System > General configuration > Advanced Settings).
