Content Import not working properly when .csv file has only a few rows of data

Problem Statement

The content import functionality is not working and gives a "select valid file" error when the .csv file being imported has only a few rows of data i.e. 3 rows or less.

Steps to Reproduce

• Create a sample content type with bare minimum 2 fields having text and wysiwyg data types.
• Try to import content for the content type, download the sample .csv from the UI.
• Try uplaoding the same sample .csv file , notice that error is observed upon clicking on preview button (Select valid file)
• Try adding 1 or 2 more rows to the .csv file and note still error is observed.
• Update the .csv file with at-least 7-8 rows of data and retry note that this time the import works fine and no errors when clicking on preview button.
