Google Scripts WebApp POST body - json

Question

I feel like there must be something obvious I'm missing, but I can't understand what is going on with how Google WebApps handle POST requests.
My script has a doPost(e) function that recieves the Post request, as I can see logged in my spreadsheet, but when I try and access the contents of the POST body it says it is called "FileUpload". How do I actually access the data within the POST body?
Below is my GS code;
function doPost(e) {
var json = e.postData.contents()
var data = JSON.parse(json)
var test = e.contentlength
var ss = SpreadsheetApp.openById("1GH1pT1BvJ-hMWrFNKUDD1KzBoEHd_TzKKk71Znk250g")
SpreadsheetApp.setActiveSpreadsheet(ss)
var sheet = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet();
var range = sheet.getRange("A1:A1");
sheet.setActiveRange(range);
range.setValue(e);
range = sheet.getRange("A2:A2")
range.setValue(json)
range = sheet.getRange("A3:A3")
range.setValue(test)
range = sheet.getRange("A4:A4")
range.setValue(data)
}
Below is the body of the POST request I am sending using hurl.it

}
This is what is logged in the spreadsheet:
{parameter={}, contextPath=, contentLength=3080, queryString=null, parameters={}, postData=FileUpload}
I recieve an error that says:
TypeError: Cannot call property contents in object FileUpload. It is not a function, it is "string". (line 9, file "Code", project "PipeDrive notifcations")
If anyone has any idea what I'm doing wrong I'd love to hear it. Thank you very much!

Answer 1

So I've fixed my issue.
I invoked .contents() on postData, however I should have just wrote .contents. Removing the () fixed my issue.
