Issue
I am Trying to implement this Stackblitz example of angular-upload-file-with-progress-bar but in my code
export class UploadDocumentTemplateComponent extends FieldType {}
I have this line because of it I'm getting this error
error TS2377: Constructors for derived classes must contain a 'super' call.
how to resolve this issue?
Solution
just in constructor you need
constructor()
{
super()
}
