Ngrx Angular - Detected unserializable action at simple object

Alllstars :

i don't get why ngrx pop this error while i'm trying to send to my api a simple object, could you give me some advice about ngrx and the reason why it refuse to serialize my object ?

I tried to put strictActionSerializability to false , no error but no object sent to my api...

Error :

Error: Detected unserializable action at "createdPath"

How i call my action :

   this.storePath.dispatch(PathActions.createPath({ createdPath }));

In actions.ts file :

export const createPath = createAction('[BOT/GROUP] CREATE PATH', props<{ createdPath: Path }>());

And my effect :

createPath$ = createEffect(() =>
this.actions$.pipe(
  ofType(PathActions.createPath),
  map(action => action.createdPath),
  exhaustMap((createdPath: Path) =>
    this.pathService.createPath(createdPath).pipe(
      map(createdPath => PathActions.createPathSuccess({ createdPath })),
      catchError(error => of(PathActions.createPathFailure({ error }))))
  )
 )
);

My object sent as JSON :

have a good day, and thanks for your help !

Andrew Allen :

For a pure data class object you can use

JSON.parse(JSON.stringify(product))

Otherwise, I suggest adding a toJSON() serialization method (which is automatically used by JSON.stringify)

public class Foo{
    private _bar:string;

    constructor(){ this._bar='Baz'; }

    get bar():string{return this._bar}

    toJSON() {
      return {bar: _bar};
    }

    static fromJSON(json) {
      ...
    }
}
