I am trying to reuse the angular components in PowerApps Component Framework. I have created the angular project inside PCF folder,bundled the angular files and used it in index.ts file.It is working in local but when I import the solution and using in model driven app it is not working.I am using angular 10. I am getting below error.

Anyone faced this issue?

Hi @Anonymous :

Please consider export your PCF Project as a unmanaged solution, then try it again, check if the issue is fixed.

If the problem persists, please refer to this post or consider creating a support ticket.

Best Regards,

Bof

This is due to bug in the UCI which conflicts with the angular component. Fix will be rolled out in upcoming deployments .

Here is workaround (but hacky 😞 ) which can be used to unblock development.

window's Promise.resolve function is overridden in UCI in a manner which makes it incompatible with Zone.js. This can be circumvented by gaining reference to an untouched definition of Promise via an iframe before the Zone.js dependency is imported:

// Address promise issue
const dummyFrame = document.createElement("iframe");
document.body.appendChild(dummyFrame);
const _innerProm_ = (dummyFrame.contentWindow as any).Promise;
document.body.removeChild(dummyFrame);
(window as any).Promise = _innerProm_;

// your code starts here
import 'myAngularProjectBundle';
