    Office 365 Groups HTTP Request
    @VivekBhatt Hey I had this same problem ( "code": "BadRequest", "message": "Empty Payload. JSON content expected." ) and ended up finding a solution so thought I'd post it here for anyone else in the future. Here is the link to the video that solved it for me: Power Apps: 🔍 Search SharePoint Lists without Delegation Issues 💪 . From like 11 min to 15 min is specifically the solution but the whole video is good for context. Essentially you need to encode the json formatted text into base 64. There isn't a built in function to do that but someone has made a powerfx With function to encode it. I will include it below. (I modified it to fix the errors) Just copy paste it into your button before the http request. Then modify the varRequestBody variable to be the JSON you need and insert varFile into that third parameter of the Http Request. Hope this helps someone!
    Set(varRequestBody,
        "{
            ""exampleColumn"": ""exampleData"",
            ""exampleColumn2"": ""exampleData2""
        }"
    );
    
    Set(varFile, "data:text/plain;base64," &
    With({
        InputText: varRequestBody,
        AsciiTable:AddColumns(Sequence(255,1),char,Char(Value)),
