Field authenticationManager in JwtAuthenticationRestController required a bean of type 'org.springframework.security.authentication.AuthenticationManager' that could not be found.

The injection point has the following annotations:
- @org.springframework.beans.factory.annotation.Autowired(required=true)

Action:

Consider defining a bean of type 'org.springframework.security.authentication.AuthenticationManager' in your configuration.

cool. Here is my code for environment.ts, as a suggestion:

export const environment = {
production: false,
api: {
url: 'http://localhost:8585',
jpa: 'http://localhost:8585/jpa',
},
};
of course, the port for your setup will not stay 8585, so feel free to adapt it heavily ;-)

You basically use it in two places, basic-authentication.service and todo-data.service. In basic there is only one instance, in todo-data a couple, so I am just posting a few lines of todo-date as an example. In your version I sort of like that it uses all UPPERCASE because those are constants. This is not the way environment.ts is implemented, though, so you would have to live with lowercase:

import { environment } from 'src/environments/environment';

...

export class TodoDataService {
...
retrieveAllTodos(username) {
return this.http.get<Todo[]>(${environment.api.jpa}/users/${username}/todos);
...
}
...
}

when we add customized RuntimeExcection("some error occurred ") .in browser's console they show error like DOCTYPE ..... something but in your video show implements like something what is that? help to solve this.
