Native federation - Angular 17: Not Found http://localhost:4201/_angular_core-17_0_5-dev.js

Question

I am working with micro frontends using native federation in Angular 17. And when I run the microfront and my host app, and I load my host app in the browser, I get the folloging error, and I don't know why.

_angular_core-17_3_12-dev.js:3806 ERROR TypeError: 404 Not Found http://localhost:4201/_angular_core-17_0_5-dev.js imported from http://localhost:4201/routes.js

And in the microfrontend console I get the folloging warning and errors:
