When getting data from PowerAutomate Flow: DataFormat.Error: We reached the end of the buffer

Hi,

I get DataFormat.Error: We reached the end of the buffer. 

When trying to do same as this example. https://janbakker.tech/use-graph-api-data-in-power-bi-using-logicapps 

(Create a Power Auromate flow to query Microsoft Grahp and get the response in Power BI)

I've tested it with diffrenet APi calls, and same throw same error.

Any help on this please?

The Power Automate flow runs ok and I can see the response.

url = "",
body = "{}",
Parsed_JSON = Json.Document(body),
BuildQueryString = Uri.BuildQueryString(Parsed_JSON),
Source = Json.Document(Web.Contents(url,[Headers = [#"Content-Type"="application/json"], Content = Text.ToBinary(BuildQueryString) ] ))
