How to solve Azure data factory Error: Sink dataset filepaths cannot contain a file name ?

I was building a pipeline which was taking data from SFTP folder and sink to Cleansed layer where file format was .parquet. As soon as validated the pipeline got the below error, where the error message is: 'Sink dataset filepath can not contain a file name, please remove the file name from {DatasetName}.

You will find error like this:

If you find this error, may get confuse at first since you have file name at two different places. One is at Sink activity settings and other one is at the data set.

Let's guide you to how to find those settings and fix this error. If you look at the Settings for Sink activity, you will find like below fig: 2.

The error message said filepath can't contain file name but remember this is not data set, it's setting of the Sink activity so you don't need to remove the file name. And if you want to keep it in a single file then choose 'Output to single file'.

So fix the issue you need click Sink and open data set as like below fig 3:

Now you can find the file name under data set as like below fig 4, Please remove file name, save and validate.

Now the error will disappear. Lesson learned, look at the error message more than once and locate the correct place to fix the issue.
