Sharepoint BannerUrl field not update

I need to update the cover image of Events (ListItem Event) on SharePoint using the Graph API. I'm using APP ONLY ACCESS mode for authentication with this endpoint:

https://login.microsoftonline.com/{{tenant_id}}/oauth2/v2.0/token

My Application has the "Sites.Manage.All" scope.

When I call the endpoint to update or create an event, if I include the "BannerUrl" field, I always get the following error:

   {
    "error": {
        "code": "generalException",
        "message": "General exception while processing",
        "innerError": {
            "date": "2024-06-28T11:50:07",
            "request-id": "a7f573a1-f7e9-49b8-9e0c-160a1d68cbf7",
            "client-request-id": "a7f573a1-f7e9-49b8-9e0c-160a1d68cbf7"
        }
    }
}

My request:

POST /v1.0/sites/{{site_id}}/lists/{{list_id}}/items HTTP/1.1
Host: graph.microsoft.com
Content-Type: application/json
Authorization: Bearer
Content-Length: 507
{
	"fields": {
		"Title": "Example",
		"EventDate": "2024-07-15 09:00:00+00:00",
		"EndDate": "2024-07-15 17:00:00+00:00",
		"Category": "Example",
		"Description": "Hello world",
		"Location": "Avenida Paulista, 1000 - Bela Vista, São Paulo, SP 01313-000, Brazil",
		"fAllDayEvent": true,
		"BannerUrl": "https://image.jpg"
	}
}

I believe there are two fields, BannerImageUrl, and BannerUrl. BannerUrl seems to be the correct one, but I always get an error when I try to define this field!

    Hi @Mateus Ferreira ,

    Sorry to hear that.

    I tested it and the situation is the same as yours. This is because we still cannot update the Hyperlink column in the SharePoint column list through the graph API.

    As a workaround, it is recommended you use rest api to update the column. For your reference:

    https://sharepoint.stackexchange.com/questions/88540/how-do-i-update-a-hyperlink-field-using-the-rest-api

    Also, I found a feedback on this issue and you can vote for it.

    Have a nice day!

    Hi @Mateus Ferreira ,

    Welcome to Q&A forum!

    Updating or creating an event with a banner image in SharePoint using the Microsoft Graph API can be tricky due to the specifics of the API endpoints and field requirements. Here are a few things to check and try out:

    1. Check Field Availability: Make sure BannerUrl is a valid field in your list. You can retrieve the list schema using the Graph API to confirm the available fields.
      
         GET /v1.0/sites/{site-id}/lists/{list-id}/columns
      
      
    2. Validate URL: Ensure that the URL provided in BannerUrl is accessible and valid.
    3. Correct Scoping: Ensure your application has the required permissions. Sites.Manage.All seems correct, but you can also try Sites.FullControl.All.
    4. Format Date Time: Ensure that the date and time format is correct. Sometimes minor formatting issues can cause errors.
    5. InnerError Details: Use the request and client request IDs provided in the error response to check logs in the Microsoft Azure portal for more detailed error information.
    6. Test Without BannerUrl: Send the request without the BannerUrl field to ensure that other fields are not causing the issue.
    7. Try BannerImageUrl: Although you suspect BannerUrl to be the correct field, it may be worth trying BannerImageUrl as well.

    If the issue persists, consider breaking down the problem:

    1. Create the Event Without the Banner: First, create an event without the banner to ensure the basic functionality works.
    2. Update the Event with BannerUrl: Then, try updating the same event with the BannerUrl. Hope this can help.
