React-bootstrap-table2: expandRow.expanded undefined

[LucaNitti]

i get this error after fetching data from remote server. The data is valid (works fine if i remove expand row).
This is how i configured all

"react-bootstrap-table-next": "^3.1.0",
"react-bootstrap-table2-overlay": "^1.0.0",
"react-bootstrap-table2-paginator": "^2.0.4",
"react-bootstrap-table2-toolkit": "^1.4.0",


        <BootstrapTable

                fetchInfo={ { dataTotalSize: this.state.totalDataSize } }
                onTableChange={ this.onTableChange }
                columns={customerColumn}
                data={customerData}
                keyField={"key"}
                containerClass={'index-customer-class'}
                noDataIndication={ () => <NoDataIndication /> }
                loading = {loading}
                overlay={_overlayFactory}
                expandRow={expandRow}
            />

           const expandRow = {

                });
                //accounts.unshift(<i className="fas fa-info-circle" data-container="body" data-toggle="popover" data-placement="top" data-content="Click on account number to search all customer that use the account."></i>);

                    </tr>)
            })}
            </tbody>
