PFA for your reference.
This error usually happens if your schema on the data source has changed (column re-named or deleted) since you have created the QuickSight dataset. You can go into ‘Edit Dataset’ and fix the error shows in data prep UI. Thanks!

Now its working fine actually there is an issue with multiple same data source with same name are there, so what happens when I chose one table from a data source and choose second tables from another data source with same name then that times this problem arises. So I just deleting the same name data source now its working fine.
Thanks Sureshde for your detail answer.
