In all such cases when you run the recipe, DSS will ask you if you want to accept schema changes. When you do this, the output dataset will have the correct number and types of columns. If you do not do this, you will get an error like you shown on the screenshot.
You can try navigating to the output dataset->Settings->Schema and hit "Check now". You should see a message to accept new schema.

Thanks for your reply! The schema seems to be good but the error wouldn't go away.
