[Solved]-Highcharts - Property value does not exist on type Point Angular 12-Highcharts

In cases when TS definitions are missing you have basically two options:

1. Cast to as any - I wouldn't recommend that.

2. Extend the existing interface with the missing property - recommended

interface CustomPoint extends Highcharts.Point {
  value: number;
}
