[Teebo]

Version info

Angular: 9.0.3 Firebase: 8.2.1 AngularFire: @angular/fire

Other (e.g. Ionic/Cordova, Node, browser, operating system):

How to reproduce these conditions

My function implementation is below

export const ssr = functions.runWith({
  timeoutSeconds: 300,
  memory: "1GB"
}).https.onRequest((request, response) => {
  require(`${process.cwd()}/dist/mot/server`).app(request, response);
});

For more defails. I also have a SO question: https://stackoverflow.com/questions/68362185/angular-universal-route-resolver-firebase-loading-timeout

Failing test unit, Stackblitz demonstrating the problem

Steps to set up and reproduce

Sample data and security rules

Debug output

Errors in the JavaScript console

Output from firebase.database().enableLogging(true);

Screenshots

Expected behavior

See the page source code when browser View page source option is cliked.

Actual behavior

The page refreshes forever without errors. Checking the error logs for the SSR function shows nothing until the function times out. It happens with specific pages not all of them.
