General Exception Using List Item Patch API Endpoint

Question

The endpoint : PATCH https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}/fields

Is not working today, we get a 'General exception while processing'. Statuscode 500

Stacktrace:

at Microsoft.Kiota.Http.HttpClientLibrary.HttpClientRequestAdapter.<ThrowIfFailedResponseAsync>d__28.MoveNext()

at Microsoft.Kiota.Http.HttpClientLibrary.HttpClientRequestAdapter.<SendAsync>d__20`1.MoveNext()

at Microsoft.Kiota.Http.HttpClientLibrary.HttpClientRequestAdapter.<SendAsync>d__20`1.MoveNext()

at Microsoft.Graph.Sites.Item.Lists.Item.Items.Item.Fields.FieldsRequestBuilder.<PatchAsync>d__4.MoveNext()

We are using .NET 8 and C#

FieldValueSet provided contains key-value:

Key = Title

Value = 123

JSON representation

{

"Title": "123"

}

This has always worked, the field we try to update is available and worked perfectly.
The resource is found, we have permissions and it's not locked.

Looks like the API Endpoint is temorary down?

Answer 1

Hello Acket, Kim (Antwerp),

Thank you for reaching out to Microsoft Support!

After testing, the endpoint works well, obviously the endpoint is not closed, the test results are as follows:

But your error code is 500, which seems to be a server-side error. Therefore, I suggest you open a support ticket with Microsoft Support to get help from the API owner.

Hope this helps.

Hi @Acket, Kim (Antwerp),

Thanks for reaching out to Microsoft!

I tried to update the listitem using Graph API-PATCH https://graph.microsoft.com/v1.0/sites/{site-id}/lists/{list-id}/items/{item-id}/fields

Checked the current status and can confirm that there is no temporary downtime for this API endpoint at the moment.

Note: Please use only valid Column Names while executing both Operations (CREATE/PATCH).

After further investigation it looks like the endpoint should return a more user friendly message, instead of a General exception while processing it should return that the document needs to be checked out before you can update the meta data.

The actual problem was that an admin had marked this Document Library as Check out required!

( Library Settings - Versioning Settings - Require documents to be checked out before they can be edited? => Yes)
