React Bootstrap Table can't create TableHeaderColumn with map Error. No any key column defined in TableHeaderColumn

Question

I get the following error when I try to create TableHeaderColumn programatically using map.

Uncaught Error: Error. No any key column defined in TableHeaderColumn. Use 'isKey={true}' to specify a unique column after version 0.5.4.

If I don't use map and hard code the same values everything works. I usually use map for tables and it usually works as a charm. I have tried with and without key property for map, same error.

Does not work:

type TableHeader = {
    dataField: string;
    name: string
    isKey: boolean
}

const crimeTableHeaders: TableHeader[] = [{
    dataField: 'CrimeCode',
    name: 'Brottskod',
    isKey: true,
},
{
    dataField: 'CrimeCodeClearText',
    name: 'Namn',
    isKey: false,
},
{
    dataField: 'Count',
    name: 'Antal',
    isKey: false,
}
]

<BootstrapTable containerStyle={{ marginTop: '10px' }} data={this.props.data} options={this.options} striped={true} hover={true} search multiColumnSearch strictSearch>
    {crimeTableHeaders.map((tableHeader, index) => {
        <TableHeaderColumn key={index} dataField={tableHeader.dataField} isKey={tableHeader.isKey} dataSort={true}>{tableHeader.name}</TableHeaderColumn>
        /*<TableHeaderColumn dataField={tableHeader.dataField} isKey={tableHeader.isKey} dataSort={true}>{tableHeader.name}</TableHeaderColumn>*/
    })}
</BootstrapTable>

Works:

<BootstrapTable containerStyle={{ marginTop: '10px' }} data={this.props.data} options={this.options} striped={true} hover={true} search multiColumnSearch strictSearch>
    <TableHeaderColumn dataField='CrimeCode' isKey={true} dataSort={true}>Brottskod</TableHeaderColumn>
    <TableHeaderColumn dataField='CrimeCodeClearText' isKey={false} dataSort={true}>Namn</TableHeaderColumn>
    <TableHeaderColumn dataField='Count' isKey={false} dataSort={true}>Antal</TableHeaderColumn>
</BootstrapTable>

This API is the solution for you React bootstrap table - keyField

<BootstrapTable data={ data } keyField='CrimeCode'>
  //Map function 
</BootstrapTable>
