flood element fromCSV showing undefined for data column values

Question

I'm trying to get flood-element to step through a number of csv records but I'm finding that some of the columns in the CSV are coming through as "undefined" and I can't see why. How do I fix this to get the City names out too?

The CSV data is:

City,Country,Id
Tokyo,Japan,1
Delhi,India,2
Shanghai,China,3
São Paulo,Brazil,4
Mexico City,Mexico,5

and the ts script reads:

import { step, TestSettings, TestData, By, beforeAll, afterAll } from '@flood/element'

export const settings: TestSettings = {
  userAgent: 'flood-chrome-test',
  loopCount: 10
  disableCache: true,
  clearCache: true,
  actionDelay: 0.1,
  stepDelay: 0.1,
}

export default () => {
    
    // Specify the shape of each record in your CSV data set
    interface AccountRow {
      City: string,
      Country: string,
      Id: int
    }
    
    TestData.fromCSV<AccountRow>("testdataA.csv");
    

    step("Create a new Account", async (browser: Browser, data:AccountRow) => {
        console.log('City:'+data.City+' Country='+data.Country+' Id='+data.Id);
    });

}

and the output is:

C:\elementflood\test1>element run test1.ts
Running test1.ts (1 of 1) with
