It seems like you're trying to perform a sort operation on a datasource in ag-Grid, and then select the first record after the sort. However, the sort operation is happening before the data is returned from the API, causing the issue.

One solution to this problem is to use a server-side sort. This means that the sort operation will be performed on the server-side, and only the sorted data will be sent to the client-side. This way, the sort operation will be performed after the data is returned from the API.

To implement server-side sorting, you can use the rowModelType option in ag-Grid and set it to 'serverSide'. You will also need to implement the getRows() method in your datasource to fetch the data from the server and return the sorted data.

Here's an example of how you can implement server-side sorting:

```javascript
var columnDefs = [/* column definitions */];
var rowData = null;

function getRows() {
  // Fetch the data from the server and return the sorted data
}

var datasource = {
  rowCount: function() {
    return rowData ? rowData.length : 0;
  },
  getRows: getRows
};

var gridOptions = {
  columnDefs: columnDefs
  When using ag-Grid with a datasource, the sorting operation is performed on the server-side, and the resulting sorted data is then returned to the client. This means that when you perform an sort operation on the grid, the data is sorted before it is returned from the API.

To select the first record after performing an sort operation, you can use the `first` property of the `api` object in ag-Grid. The `first` property returns the first record in the sorted data.

Here is an example of how you can use the `first` property to select the first record after sorting:
```
// assume'myApi' is a valid datasource
const firstRecord = myApi.getData().first();
```
This will return the first record in the sorted data.

Alternatively, you can use the `sort` method of the `api` object to sort the data on the client-side, before selecting the first record. This can be useful if you want to perform additional processing on the data before selecting the first record.
```
// assume'myApi' is a valid datasource
myApi.sort({
  columnId:'myColumn',
  ascending: true
});
const firstRecord = myApi.getData().first();
```
This will sort the data on the client-side based on the `myColumn` column, and then
