I’m working on a Spring Boot application using Vaadin for the frontend and Spring Security for authentication. I'm encountering an issue where Vaadin's internal XHR requests are being blocked with a 403 Forbidden error after login.

`
The error details from the browser console are as follows:

FlowClient-341d667e.js:3 POST http://localhost:8085/?v-r=uidl&v-uiId=3 403 (Forbidden)

FlowClient-341d667e.js:1 Server returned 403 for xhr
FlowClient-341d667e.js:1 Reconnecting because of XHR failure
FlowClient-341d667e.js:1 Reconnect attempt 1 for XHR
FlowClient-341d667e.js:3 Re-sending last message to the server...
FlowClient-341d667e.js:1 Sending xhr message to server: {"csrfToken":"f1fea950-67a6-4c85-9760-3c5b43b27602",
"rpc":[{"type":"publishedEventHandler","node":1,"templateEventMethodName":"connectClient",
"templateEventMethodArgs":["admin/login","","",null,""],"promise":0}],"syncId":0,"clientId":0}`

What I’ve Tried 1.Disabling CSRF entirely: http.csrf(AbstractHttpConfigurer::disable);

2.Configuring CSRF to ignore specific Vaadin endpoints:

`http.csrf(csrf -> csrf
    .ignoringRequestMatchers(
        "/admin/**", "/admin/trading-accounts", "/admin/algoSignals", "/vaadinServlet/**", "/VAADIN/**", "/frontend/**", "/frontend-es5/**", "/frontend-es6/**")
);`

3.Allowing Vaadin internal requests using HandlerHelper.isFrameworkInternalRequest:

`authorizeRequests(auth -> auth
    .requestMatchers(request -> HandlerHelper.isFrameworkInternalRequest("/*", request)).permitAll()
    .requestMatchers("/admin/trading-accounts", "/admin/algoSignals").authenticated()
    .anyRequest().permitAll()
);
`

This also doesn’t resolve the problem.
