Get 'UnableToDeserializePostBody' error after sending a post request to Microsoft Germany endpoint

After sending the following post request to Microsoft Germany endpoint (https://graph.microsoft.de/v1.0), I got 400 UnableToDeserializePostBody, but I received 201 after I sent the same request to Microsoft Graph endpoint (https://graph.microsoft.com/v1.0).

Is there limitation on Germany endpoint?

Another reason you may get a UnableToDeserializePostBody from this endpoint is the recurrence startDate/endDate - they cannot be in the DateTime format.

In other words, a date in the ISO8601 format ("yyyy-MM-ddTHH:mm:ss") will also cause this error.

The date should be formatted as "yyyy-MM-dd".

Can't believe it's that picky, especially since the documentation insists the date has to match the event dateTime, but that's how it is.

I ran into the same issue, and as louisl mentioned it was a problem with using the wrong primitive types in the request object.

I found this library of Typescript Types for the Microsoft Graph Client: https://github.com/microsoftgraph/msgraph-typescript-typings. This library provided the "Event" type, which is what I believe you're using.

Below is a snippet of Typescript that helped me ensure my request object was correct. Notice the Event import and the explicit typing of the eventRequest constant.

import { Event, Attendee } from '@microsoft/microsoft-graph-types'

      const eventRequest: Event = {
        subject: name,
        body: {
          contentType: 'html',
          content: ...
        },
        ...
      }

If you're using VSCode and a Mac you can command + click on the type to look at the definition directly, so you can see what properties are optional, and what types they require. I found Microsoft's type library and in-line comments to be more up-to-date than the official documentation.

It's really useful to explore the type file to get a better idea of how the Microsoft Client works. This principle has been helpful with other libraries as well.

You've probably given up or fixed it by now but I just had this error when setting color. I used an integer but when I changed to string it was ok.

I notice you have "reminderMinutesBeforeStart":15 try it as "reminderMinutesBeforeStart":"15".
