What could be the possible reason? This is my Image and getRows code

getRows: (params: IServerSideGetRowsParams) => {
                const { startRow, endRow, sortModel, filterModel } = params.request;
                if (startRow === 0 && initialRender) {
                    getDashboardTableData({
                        variables: {
                            result: 'ProjectSummary',
                            startRow: startRow,
                            endRow: endRow,
                            tab: state.tab,
                            headerFilter: state.card,
                            filtergroup: JSON.stringify(state?.defaultFilter),
                            sortModel: JSON.stringify(sortModel?.length ? sortModel[0] : {}),
                        },
                    }).then((response) => {
                        if (response?.data) {
                            const { datarows, total } = JSON.parse(response?.data?.lpapqpprojectsumm.body);
                            if (response?.data?.lpapqpprojectsumm?.statusCode === '200') {
                                params?.success({
                                    rowData: datarows,
                                    rowCount: total,
                                });
                            }
                        } else {
                            params?.fail();
                        }
                    }).catch((error) => {
                        params?.fail();
                    });
                }
