Sharepoint List Output; Error Encountered: An item with the same key already been added.

Hi,

I get the error message for SharePoint List Output, Error Encountered: An item with the same key already been added.

My workflow is that when the condition meets, Alteryx will replace the content from "A" to "B" in a column. And after that, it linked to sharepoint list output.

It was working fine, but I changed something in that specific coulmn and then suddnely not working.

I deleted that column and made a new column with the same name, but still get that error message..

Anyone has idea how to tackle this?

Does anyone other than your workflow edit this list?

@patrick_mcauliffe Hi Patrick, thanks for your reply.

Yes, I made an amendment that SharePoint Designer will update the column from "C" to "D",

while Alteryx will update the column from "A" to "B". Then I noticed with this amendment, Alteryx Workflow is not working anymore.

So I deleted the workflow in Designer,, still wasn't working.

So deleted that column and made a new column with the same name again, but not working.

Do I need to make sure anything else is not editing the list? and perhaps to use this workflow again, I need to make a list again??

@hayley93 I would try creating a new list as a test with the workflow.  This would allow you to narrow down if it's a permissions issue within Sharepoint or a process issue in the workflow.
