Angular code compilation failed after making changes for autocomplete tag in Appstream - AWS Blu Age L3 Workshop

Here is the solution file. Maybe your OptionImpl class declaration is after @Component declaration and cause the issue.

import { Component } from '@angular/core';
import { Overlay } from "./../commonMap/overlay";
import { Option } from "../../dynamic-field/custom/dynamic-autocomplete.component";

export class OptionImpl implements Option {

    constructor (value: string, label: string) {
        this.value = value
        this.label = label
    }

	value : string;
    label: string;
}

@Component({
    moduleId: module.id,
    selector: 'comen01-comen1a',
    templateUrl: './comen01-comen1a.component.html'
})
export class Comen01Comen1aComponent extends Overlay {
    trnname: any = {};
    title01: any = {};
    curdate: any = {'value': 'mm\/dd\/yy'};
    pgmname: any = {};
    title02: any = {};
    curtime: any = {'value': 'hh:mm:ss'};
    optn001: any = {};
    optn002: any = {};
    optn003: any = {};
    optn004: any = {};
    optn005: any = {};
    optn006: any = {};
    optn007: any = {};
    optn008: any = {};
    optn009: any = {};
    optn010: any = {};
    optn011: any = {};
    optn012: any = {};
    option: any = {};
    errmsg: any = {};

    public FIELDS: string[] = ['trnname', 'title01', 'curdate', 'pgmname', 'title02', 'curtime', 'optn001', 'optn002', 'optn003', 'optn004', 'optn005', 'optn006', 'optn007', 'optn008', 'optn009', 'optn010', 'optn011', 'optn012', 'option', 'errmsg'];

    ngAfterViewInit(): void {
    }

    getMenuOptions (): Option[] {
        let menuOptions : Option[] = []

        return menuOptions
