SQL reporting invalid syntax when run in Power BI

I have written an SQL script which runs fine when executed directly in SQL Management Studio. However, when entering it into Power BI as a source, it reports that it has an incorrect syntax.

This is the query:

            EXEC "dbo"."p_get_bank_balance" '2'
