Error in developing the tutorial custom Visual

Hi Power BI community !

I'm trying to learn how to develop my own custom visual. I first start to do the turial in the Github.

And I have a problem when I add databinding to Bar Chart.

Indeed, when I compile it' says that value and category are incompatible when I push the data in barChartDataPoints.

error TYPESCRIPT /src/barChart.ts : (58,37) Argument of type '{ category: string | number | boole
an | Date; value: string | number | boolean | Date; }' is not assignable to parameter of type 'BarCh
artDataPoint'.
Types of property 'value' are incompatible.
Type 'string | number | boolean | Date' is not assignable to type 'number'.
Type 'string' is not assignable to type 'number'.

58: barChartDataPoints.push({
category: category.values[i],
value: dataValue.values[i]
});

Can anyone help me ? thank you for advance.

@Ghislain,

I see you've solved this problem in this thread. For more information, see TypeScript Type assertions.
