Request 'GET /sw.js' doesn't match 'POST /login Spring Security - spring

Question

I am running Spring Boot v2.3.2.RELEASE, Spring v5.2.8.RELEASE and after a successful login I get Request 'GET /sw.js' doesn't match 'POST /login. This happens in Chrome but not in Firefox.
This is my security config class:
#Configuration
#EnableWebSecurity
public class WebSecurityConfig extends WebSecurityConfigurerAdapter {
private static final Logger log = LoggerFactory.getLogger(WebSecurityConfig.class);
#Autowired
private LdapAuthenticationProvider authProvider;
/**
* Defines the web based security configuration.
*
* #param http It allows configuring web based security for specific http requests.
* #throws Exception
*/
#Override
protected void configure(HttpSecurity http) throws Exception {
http
.authorizeRequests()
.antMatchers("/css/**", "/js/**", "/images/**").permitAll()
.anyRequest().fullyAuthenticated()
.and()
.formLogin()
.loginPage("/login") //custom login page
.permitAll(); // permit everyone the /login page
}
/**
* Sets a custom authentication provider.
*
* #param auth SecurityBuilder used to create an AuthenticationManager.
* #throws Exception
*/
#Override
protected void configure(AuthenticationManagerBuilder auth) throws Exception {
auth.authenticationProvider(authProvider);
}
My home controller is:
#RequestMapping("/")
public String index(Principal principal) throws IsimConnectionException {
Authentication authentication = (Authentication) principal;
if ((authentication.getPrincipal() != null) && (authentication.isAuthenticated())) {
...
My login controller is:
#Controller
public class LoginController {
#GetMapping("/login")
public String login(){
return "login";
}
}
Here is my stack:

Can you please suggest what is missing in my configuration?
Update:
This is the network screenshot when the error appears from Chrome:
