@Naveen It should be expression value and not copy paste the expression directly in the from body.
Remove the value and Click on your From text box and there would be one pop up and then click on expression.
Now use the value that I provided and paste it and click on OK.
Note: The value could be changed inside body as per your name of the action.
body('Execute_a_SQL_query_(v2)')?['resultsets']?['Table1']}
