Error: This project item doesn't belong to correct owner

I have this mutation:


$query = <<<gh
  mutation AddIssueToProject {
  addProjectNextItem(input:{contentId:"MDU6SXNzdWUyMzEzOTE1NTE=",projectId:"PN_kwDOAa21V80YVQ"}) {
    projectNextItem {
      id
    }
  }
}

And when I run this I get this error This project item doesn't belong to correct owner.

I can add that issue to that board via the web. I’ve tried two diff tokens, one of them the org owner.

Any ideas what this could be?

Seeing same issue trying to add PR to a project (beta) on a different org. Works fine via UI by pasting the URL of the PR, but get ‘This project item doesn’t belong to correct owner’ when trying via graphql
