The requested user 'chrisb#domainname.com' is invalid - microsoft-graph-api

Question

Microsoft Graph sometimes returns a strange result
Client Error:
GET https://graph.microsoft.com/v1.0/me/calendars resulted in a 404 Not Found
{
"error": {
"code": "ErrorInvalidUser",
"message": "The requested user 'chrisb#domain_name.com' is invalid.",
"innerError": {
"request-id": "c229f76d-a9d0-4441-b663-b34f4996cddb",
"date": "2017-11-21T01:23:18"
}
}
}
That issue seems to be strange for me, since I know the user exists since I can login under it.
What I do:
I use stored refresh token to get access token.
Using that access token I try to get list of all user calendars.
At that point it return me fail message.
Question:
What does that error mean - since user is 100% present at Microsoft (I able to get auth token from refresh token and able to login under that user)

Answer 1

I had faced same issue for some MS users only whom specially has very old account, I was passing email of microsoft user like : following
let userInfo = {email: user.email}
let apiParams = {token: access_token, event: newEvent,calendarId: msUserInfo.calendarId, user:userInfo}
Solution:
After I had issue, I have remove 'user' parameter from api and it works for me.
I have set now as following.
I have used Node, node-outlook
const outlook = require('node-outlook');
let newEvent = {
"Subject": objUpdate.title,
"Body": {
"ContentType": "HTML",
"Content": objUpdate.description
},
"Start": {
"DateTime": moment('startDate').toISOString(),
"TimeZone": objUpdate.timeZone
},
"End": {
"DateTime": moment('endDate').toISOString(),
"TimeZone": objUpdate.timeZone
}
};
outlook.calendar.createEvent({token: access_token, event: newEvent ,calendarId: msUserInfo.calendarId
},async function(error, result){
if (error) {
console.log("error: -",error)
throw "Microsoft Calendar Api Err."
}else if (result) {
console.log("Result -")
}
});
