CloudScript fails when accessing URL property in object
I'm trying to use CloudScript to get the URL of my Facebook profile picture so I can set it as my PlayFab Avatar.
/*{ // This is the JSON structure returned by the http request
"picture": {
"data": {
"height": 50,
"is_silhouette": false,
"url": "https://platform-lookaside.fbsbx.com/platform/profilepic/?asid=10155832140626538&height=50&width=50&ext=1537585061&hash=AeRvbpI6EulgctDz",
"width": 50
}
},
"id": "10155832140626538"
}*/
var url = "https://graph.facebook.com/me/?fields=picture&type=square∾cess_token="+authToken;
var method = "get";
var contentBody = "";
var contentType = "application/json";
var headers = {};
var responseString = http.request(url,method,contentBody,contentType,headers);
var payload = JSON.parse(responseString);
return (((payload || {}).picture || {}).data || {}).url;
I can access the "picture" and "data" property of the JS object, but never the "url". I can even access the "height", "is_silhouette", and "width" properties by replacing "url" with those properties.
But ... when I access the "url" property, the code stops working, throwing
{
"FunctionResult": null,
"Logs": null,
"ExecutionTimeSeconds": 0,
"MemoryConsumedBytes": 0,
"APIRequestsIssued": 0,
"HttpRequestsIssued": 0,
"Error": {
"Error": null,
"Message": "There was a problem running testPic. Check your arguments and try again.",
"StackTrace": null
}
}
Is PlayFab blocking or reserving the "url" keyword? I know it's not a JS thing because JS doesn't behave this way, and the code works fine outside of PlayFab.

No, we don't block or reserve URL (or url). Can you write your payload to the log, to see what it actually contains?
{
"FunctionResult": null,
"Logs": [
{
"Level": "Debug",
"Message": "{\"picture\":{\"data\":{\"height\":50,\"is_silhouette\":false,\"url\":\"https://platform-lookaside.fbsbx.com/platform/profilepic/?asid=10155832140626538&height=50&width=50&ext=1537597911&hash=AeSK7VTnDou3sTUJ\",\"width\":50}},\"id\":\"10155832140626538\"}",
"Data": null
}
],
"ExecutionTimeSeconds": 0.193594,
"MemoryConsumedBytes": 32456,
"APIRequestsIssued": 0,
"HttpRequestsIssued": 1,
"Error": null
}
It works fine on a JS editor:

Actually, I'm finding that you get the same result trying to return is_silhouette. The problem is due to the return being unable to handle the value itself. It works for me if you stringify the value you're returning:
var urlString = JSON.stringify(payload.picture.data.url);
return urlString;
