I am working on a Spring Boot application and facing an issue with the CSRF filter. Despite disabling CSRF in my security configuration, I keep receiving the error “Invalid CSRF token found” when trying to make a POST request to my registration endpoint.

Here is my SecurityConfig class configuration:

@Configuration
@EnableWebSecurity
@RequiredArgsConstructor
public class SecurityConfig {

    private final JwtAuthenticationFilter jwtAuthenticationFilter;
    private final AuthenticationProvider authProvider;

    @Bean
    public SecurityFilterChain securityFilterChain(HttpSecurity http) throws Exception {
        return http
                .csrf(csrf -> csrf.disable())
                .authorizeHttpRequests(authRequest -> authRequest
                        .requestMatchers("/auth/**").permitAll()
                        .anyRequest().authenticated())
                .sessionManagement(sessionManager -> sessionManager
                        .sessionCreationPolicy(SessionCreationPolicy.STATELESS))
                .authenticationProvider(authProvider)
                .addFilterBefore(jwtAuthenticationFilter, UsernamePasswordAuthenticationFilter.class)
                .build();
    }
}```java

I tried the following:

1. Disabled CSRF using csrf().disable() in my SecurityConfig.
2. Disabled CSRF using .ignoringRequestMatchers("/auth/**") in my SecurityConfig.
3. Made POST requests to /auth/register using Postman.

Despite these steps, I continue to receive a 401 error indicating an invalid CSRF token. I have also checked the server logs and confirmed that the CSRF filter is still active.
