There are a few issues that I'm struggling to resolve.

I am utilizing SwaggerService to fetch data, but the response is coming back as undefined.

import {SwaggerService} from '../../services/swagger.service';

export class TestComponent implement OnInit {
  public mydata:Object;

  constructor(public readonly service: SwaggerService)
  {
     this.service = this.service['GetData'].get().subscribe(
      data=>{
          this.mydata['data']=data;
      },
      error=>console.error(error)

     );
   }
}

The problem lies in the fact that data returns an array with values, yet this.mydata['data'] returns an empty array - it's undefined.

This service is sourced from a .NET controller and upon inspection in Chrome debugger, the data is indeed present.

Should I consider implementing some form of mapping?

Answer №1

It seems that the issue here lies in the fact that your mydata variable has not been properly initialized. While you've declared mydata as an Object, it will actually start off with a value of undefined until it is assigned a value.

To resolve this, try initializing mydata to an empty object, which should address the problem at hand.

Note: As pointed out by @Narm and underscored in the link provided, consider using the non-primitive object type over Object.

public mydata: object = {};
