Hi @Tonti
I'm glad to hear you solve the problem, if you have any issue about MS Graph Booking, you are welcome to raise a ticket in this forum.
By the way, since the Microsoft Q&A community has a policy that "The question author cannot accept their own answer. They can only accept answers by others." and according to the scenario introduced here: Answering your own questions on Microsoft Q&A, I would make a brief summary of this thread:
Updating bookingstaffmember microsoft.graph.bookingWorkTimeSlot object error
Solution:
The problem is the "@odata.type":"#microsoft.graph.bookingWorkTimeSlot" object is different in the production and beta versions of the api.
Beta version:
{
"@odata.type":"#microsoft.graph.bookingWorkTimeSlot",
"start":"08:00:00.0000000"
"end":"10:00:00.0000000"
}
Production version:
{
"@odata.type":"#microsoft.graph.bookingWorkTimeSlot",
"startTime":"08:00:00.0000000"
"endTime":"10:00:00.0000000"
}
