Giving error in chrome like cannot read properties of undefined in Angular

Created two web components: web-comp-1, web-comp-2

When I tried to add in HTML page, I am getting console error like below

Uncaught TypeError: Cannot read properties of undefined (reading 'create')
at new m.<computed> (web-comp-1.js:3:2706)
at new t (web-comp-1.js:3:12616)

When I checked the line, the code is,

(o = (u = F && 1 === a.create.length) ? Reflect.construct

Generated web component using below versions and angular elements: "@angular/animations": "14.2.7", "@angular/cdk": "14.2.5", "@angular/common": "14.2.7", "@angular/compiler": "14.2.7", "@angular/core": "14.2.7", "@angular/elements": "14.2.7",

If you run in stack blitz, you wont see any error, you need to download the project and open in only "Chrome". This issue happening only in chrome, not in mozilla

Solution

  • Two solutions:

    a) Upgraded document-register-element package from 1.7.2 to 1.14.10 in package json, the error gone away. Thank you @Abolfazl Almas, your link triggered me an idea

    OR

    b) Remove document-register-element package (deprecated) and add "@ungap/custom-elements" and change in angular.json file like below, wherever you see document-register-element file path:

    "scripts": [{
            "input": "node_modules/@ungap/custom-elements/index.js"
 ]}
