Flow to save Message Center messages in SharePoint list is giving error on Duplicate messages.

Hi Team,

I am trying to create a Flow to save Message Center messages in SharePoint list is giving error on Duplicate messages. I had this flow earlier which was fetching data from Office365 API's which is now deprecated, which is why I am building it from scratch using Graph API.

Three stages I have divided it:

Extracting Message center data from Graph API

Channel the data in right format from JSON to SharePoint list.

Make sure, no duplicate message keeps flooding the List.

The first two stages are all good. I can save messages in a SharePoint list. But then I noticed, if I leave it at that, there are lot of same duplicate messages updated with the same ID number.

That is when I tried to filter the messages from the existing SharePoint list & its failing ever since.

Earlier, when I used Office365 API's to get messages, I had the same issue, but setting SharePoint Column with Unique vales, helped me stop duplicate messages. The same formula somehow does not work this time.

The flow fails saying "An action failed. No dependent actions succeeded."

Meaning, because it cannot save Duplicate values in SharePoint it will not allow the rest of the flow to run. If i remove the condition of comparing & filtering duplicate values, then all data gets saved in list perfectly, with all sorts of Duplicates.

Here are some details:

Flow picture:

The condition area with SharePoint item creation looks this way:

In the body it says:

{

  "status": 400,

  "message": "The list item could not be added or updated because duplicate values were found in the following field(s) in the list: [Title].\r\nclientRequestId: ac822f12-45b8-489c-81ba-ee21a95b0f9b\r\nserviceRequestId: ac822f12-45b8-489c-81ba-ee21a95b0f9b"

}

In the SharePoint list, this is the Column which is holding unique values, which is compared with the new incoming ID values:

Any help in the right direction would be great.

Thanks
