MS Bookings API Error - GET /solutions/bookingBusinesses/{business-id}/customers/{id}

Question

Hello,

I'd need some assistance with an issue I'm encountering with MS Bookings API, that suddently stopped working today.

The issue is kind of similar to this one posted earlier today.

On my case, it happens with GET requests sent to the endpoint /solutions/bookingBusinesses/{business-id}/customers/{id}.

I get a 500 Internal Server Error, and the following error message.

{
    "error": {
        "code": "ErrorInternalServerError",
        "message": "An internal server error occurred. The operation failed., Unable to cast object of type 'System.Collections.Generic.List`1[Microsoft.Exchange.Data.StoreObjects.StorePropertyDefinition]' to type 'System.Collections.Generic.ICollection`1[Microsoft.Exchange.Data.PropertyDefinition]'.",
        "innerError": {
            "date": "2023-03-27T16:51:50",
            "request-id": "9b554be7-eca7-4d97-a12f-deb4ad9296b8",
            "client-request-id": "9b554be7-eca7-4d97-a12f-deb4ad9296b8"
        }
    }
}

Could you please help me on this issue and provide a solution to make it work?

Thank you very much.

Hello Dorian Bourcet,

I'm also getting the same error '500 Internal Server Error' while trying to execute the Get bookingCustomer graph API, which is not an expected behavior. I would recommend you raise a support case with Microsoft Graph, a Support Engineer will be able to assist you better. You can raise support ticket from
https://aad.portal.azure.com/ or https://admin.microsoft.com/#/support/requests.

Hope this helps.
