Describe the bug

When we signup on the production and the screen appears where we put our username and agree to the T&C, some of the console errors are reported. These errors appears when the "classroom-promos" config property is enabled.

Important: After resolving the issue, add the error catch block to the validateAccessToClassroomPage and fetchClassroomDataAsync present in the ngOnInit function of side-navigation-bar.component.ts and top-navigation-bar.component.ts.

Steps To Reproduce

On prod:

1. Signup with the unregistered account and reach to the signup page.
2. Look at the console

On dev:

1. Login with the admin account and enable the classroom promos config property.
2. Logout and try to signup with a new account and notice the error in the console.

Expected Behavior

There should be no errors.
