Class with Enum field leads to a TypeError

[arbue]

Hi @nartc,

currently I am using the automapper-transformer-plugin in combination with nestjs. It works great for all of my types as indended, but if I create a class with an enum type the compiler throws a TypeException.

Error:

 TypeError: Cannot read property 'transformFlags' of undefined

A workaround is to add the @AutoMap() annotation manually to the enum field.

Could you look into this issue.

Versions:
NestJs: 7.0.0
nestjsx-automapper: 3.1.0
@nartc/automapper-transformer-plugin: 1.0.20
typescript: 3.7.4

Not working example:

enum State {
  READY,
  STOPED
}

export class ExampleEntity {
  state: State;
  id: number;

  constructor() {
    this.state = State.READY;
  }
}

Working example:

enum State {
  READY,
  STOPED
}

export class ExampleEntity {
  @AutoMap() state: State;
  id: number;

  constructor() {
    this.state = State.READY;
  }
}

Thanks for reporting. Recently, TS has a couple of releases and the latest release is a major version bump. This transformer plugin also has some problem with inheritance as well which I'll look into. However, I'm pretty busy with work currently so the earliest I can take a look is next weekend. Sorry for any inconvenience :)
