In AuthorReviewerGridCellProvider:

        if ($columnId == 'actions') {
            switch ($this->getCellState($row, $column)) {
                case ReviewAssignment::REVIEW_ASSIGNMENT_STATUS_COMPLETE:
                case ReviewAssignment::REVIEW_ASSIGNMENT_STATUS_THANKED:
                case ReviewAssignment::REVIEW_ASSIGNMENT_STATUS_RECEIVED:
                    $user = $request->getUser();
                    return [new ReviewNotesLinkAction($request, $reviewAssignment, $submission, $user, 'grid.users.reviewer.AuthorReviewerGridHandler', true)];
                default:
                    return null;
            }
        }

Needs to change to, as template expects array.

        if ($columnId == 'actions') {
            switch ($this->getCellState($row, $column)) {
                case ReviewAssignment::REVIEW_ASSIGNMENT_STATUS_COMPLETE:
                case ReviewAssignment::REVIEW_ASSIGNMENT_STATUS_THANKED:
                case ReviewAssignment::REVIEW_ASSIGNMENT_STATUS_RECEIVED:
                    $user = $request->getUser();
                    return [new ReviewNotesLinkAction($request, $reviewAssignment, $submission, $user, 'grid.users.reviewer.AuthorReviewerGridHandler', true)];
                default:
                    return [];
            }
        }
