I have to set the EventDate column, I have set as EventDate or [EventDate] or EventDate [CustomColumn];

And facing Error as-

The site or list column "[EventDate]" does not exist or is not valid.

Answer 1

Based on our conversation above and at the discussion .

The issue is related to your code for this field in your custom Item Style.

You should be aware of the internal column name that you have used in your custom Item Style. should be the same internal Column name at your List.

Answer 2

Actually the column's internal name is different StartDate. Now it's working fine.
