'Bar' is considered a Material chart.

vs. 'BarChart', which is a Classic chart.

with Material charts, an options conversion method needs to be used...

google.charts.Bar.convertOptions

which means you would need to access the google.charts namespace.

options={google.charts.Bar.convertOptions({
  chart: {
    title: 'Spend Uplift',
  },
  colors: ['#FB7A21'],
  backgroundColor: 'red'
})}

You need to use chartType as BarChart. For some reason, Bar seems to cause issues. In case you want the chart bars to be vertical, change it to ColumnChart.
