query level date parameter

Hi,

Issue with passing a date parameter to the SQL query in Power BI. 

I have created a parameter with date data type, trying to pass that date param to the query but received a conversion error.

SQL query:

Select * from table1 where created_date <= '" &StartDate& "'

Created_date in the table is in date format.

StartDate parameter also is in date format.

Error message: 

Message=Conversion failed when converting date and/or time from character string.
Number=241
Class=16

Thanks
