Unable to retrieve user's mysite URL OneDrive explorer javascript problem

I have some strange problem with onedrive explorer:
https://github.com/OneDrive/onedrive-explorer-js
I have configured my app credentials, have added the permissions:
Files.Read
Files.Read.All
offline_access
profile
Sites.Read.All
User.Read
and get this error:
https://graph.microsoft.com/v1.0/me/drive/root?expand=thumbnails,children(expand=thumbnails(select=large))
502
Bad Gateway
additional error text:
Unable to retrieve user's mysite URL.
I have tried with 3 different accounts.
Additionally, on graph explorer I have an error :
Must be authenticated to use '/drive' syntax (It gives my profile details and nothing else) from -
https://developer.microsoft.com/en-us/graph/graph-explorer
Can somebody let me know what could be the problem?
Thank you !

Problem is in the azure subscription, not in any of the accounts. I have created new subscription and all is fine. Seems that this use case or test cannot be done for free.
Thanks for the collaboration :)

Can't correctly obtain OAuth to append to google sheet via Javascript http request

I can't for the life of me append to my google sheet via http request. More specifically I can't seem to get the Oauth formatting right. I don't want/need a uri or prompt for permission as its just me managing my own spreadsheet. First, I was trying with just my api key, but then found out that if you're editing data you need to obtain an access token. That's when I started trying to obtain the token through oauth2 following the TERRIBLE google api documentation. That's where I hit a wall and have just about given up. It's such a simple concept, I just want to add data to my spreadsheet on drive from an online script (housed on scriptr.io), but Google yet again makes things so unneccessarily complicated and don't help matters with their convoluted, misleading, and scattered documentation. Can someone please help me in accomplishing this? Here's where I'm at or what progress I've made thus far.
I've figured out how to correctly format the call to add a row of data to the spreadsheet.
POST https://sheets.googleapis.com/v4/spreadsheets/-/values/Raw%20Data!A1:D1:append?valueInputOption=USER_ENTERED
//Header
Authorization: Bearer {oauth_token}
//Payload
{"range": "Raw Data!A1:D1","majorDimension": "ROWS","values": [["Test", "$15", "2", "3/15/2016"]]}
I know the above works because I've successfully added the data using the OAuth 2.0 Playground. However, when trying it outside of the playground (on a rest client) I keep getting errors trying to obtain the token.
POST https://www.googleapis.com/oauth2/v4/token
scope=https://www.googleapis.com/auth/spreadsheets
client_id=------&
client_secret=-----&
refresh_token=-----&
grant_type=refresh_token&
access_type=offline
I use the client id & client secret from my api console and I use the refresh token I got by authorizing the spreadsheet api in the oauth playground, but the above POST request leads to the following error
Error 400
{
"error": "unsupported_grant_type",
"error_description": "Invalid grant_type: "
}
Can someone please help me figure out how to correctly do this?

How to get the posts of the news feed with graph api javascript

I want to get my Facebook news feed in order to filter depending on some options.
But when I ask for permission as below, read_stream is not accepted, I 'm getting "Invalid Scopes: read_stream"
FB.login(checkLoginStatus, {scope:'read_stream,email,publish_actions, user_friends, user_posts '});
Looking around in Internet, I found out that this permission has to be required from Facebook.
Any workaround for that would be much appreciated.

The permission read_stream was deprecated with v2.4. You wouldn't have gotten it granted during Login Review anyway.
Basically, /{user_id}/home endpoint with the newsfeed is no longer accessible. If you want to use /{user_id}/feed, that should work, but this only contains the user's own timeline.
See
https://developers.facebook.com/docs/apps/changelog#v2_4

Importing events from MS Office 365 (PHP)

I have an intranet site for a small medical clinic, and on the front page I want to display upcoming events associated with the clinic-wide MS Office 365 email account.
I'm new to APIs, so some resources on how to get started would help.
The site is in PHP, but as I understand it, API functions can be done in JavaScript - either way is fine.
Once I can get an XML or JSON file from Microsoft, I'm pretty sure I can figure out how to format it for the site. The problem is just getting the info.
So far I have:
<script>
var req = new XMLHttpRequest();
req.open("GET", "https://outlook.office365.com/api/v1.0/users/{email address}/events", false);
req.send();
console.log(req.status);
console.log(req.StatusText);
</script>
The console logged:
"NetworkError: 401 Anonymous Request Disallowed
I've also tried the line req.open("GET", "https://outlook.office365.com/api/v1.0/users/me/events", false{or true}/ {username}, {password});, to which the console logged
NS_ERROR_DOM_BAD_URI: Access to restricted URI denied
Almost all the documentation I can find is directed toward individual users (employees of a company) interfacing with their 365 accounts through some web-based interface, so almost all of the urls have /me/ in them, indicating they have authenticated somehow. But I want my PHP or JavaScript script to automatically authenticate a single user and retrieve information. I imagine this requires hard-coding the user and password somewhere, but I've found no examples like that.
I'm obviously in way over my head, but can anyone offer any advice on how I can get this done? Or read more about how APIs work? Most of the documentation out there is directed at people who already have a certain level of knowledge, which I don't have, and don't really know how to get.
Thanks.

Missing part is authentication (OAuth) to connect from your app to O365..
Maybe this helps http://msdn.microsoft.com/library/bde5647a-fff1-4b51-b67b-2139de79ce4a%28Office.15%29.aspx

Yes, you do need to authenticate against the Office 365 APIs as indicated previously. To make calls against Office 365, you must register your app for OAuth against Azure AD.
I'd suggest looking at http://dev.office.com/getting-started/office365apis. It should guide you through setting up authentication and show you how to make the rest call.

Facebook Feed Dialog: Post not showing up on friend's wall even though I get a response id

I am creating an app on facebook and I am trying to post to a friend's wall. I'm using the facebook javascript SDK and the FB.ui method to do this. In short here is my code:
function test() {
var obj = {
method: 'feed',
to: '######'
};
function callback(response) {
alert(response['post_id']);
}
FB.ui(obj, callback);
}
Note that I made this code very simple for testing purposes.
When I run it, a facebook feed dialog opens correctly and at the top says "Post Story to friendsname's Wall". I type in a message and press Share. My alert pops up with a response['post_id'] number. Because there is a response['post_id'] the story should've been posted successfully right? However when I navigate to the friend's wall there is no story. I've tried this multiple times in slightly different ways and haven't been able to get it to work. If I remove the 'to' parameter and simply post to my own wall it -does- work. So for some reason, posting to a friend's wall breaks it?
I know it's a rather broad question but I was wondering if anybody had any ideas why this doesn't work. Thanks

I suspect the problem may be because your application is in sandbox mode - https://developers.facebook.com/docs/ApplicationSecurity/
When testing your apps, place them into Sandbox Mode. This hides your
app entirely from all users who you have not authorized in the
developer app to see the app, for the roles described below. Please
note that when your app is in Sandbox Mode, you cannot call any API
calls on behalf of users who cannot see your app.
Basically, if your application is in sandbox mode, nothing your application does can be seen by users who have not authorized your application or by users that have not been specifically listed in the "roles" within your applications settings.
Remove you application from sandbox mode or add some users to specific "roles" within your application.
