String reference not set to an instance of a String

Hi everyone,


I wanted to connect to a web API from Power BI Desktop. While the URL works in the browser and returns data, it is not the case when trying with Power BI Desktop. I get the error of String reference not set to an instance of a String Parameter name : s


Does anyone know how to fix this?
