504-Gateway timeout with error as listed above

Steps to reproduce

@Configuration
@Order(1)
public class SecurityConfigDB extends WebSecurityConfigurerAdapter {
	
	@Override
    protected void configure(HttpSecurity http) throws Exception {
		
		http.cors().configurationSource(corsConfigurationSource());
		http.csrf().disable();
				
        http.antMatcher("/api/**").csrf().disable()
                .exceptionHandling()
                	.authenticationEntryPoint(authenticationEntryPoint)
                	.accessDeniedHandler(accessDeniedHandler)
                .and()
                .sessionManagement()
                .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
                .and()
                .authorizeRequests()
                .antMatchers(AUTH_WHITELIST).permitAll()
                .anyRequest()
                .authenticated()
                 ;       
                
        http.addFilterBefore(jwtAuthenticationFilter(), UsernamePasswordAuthenticationFilter.class);
    }
	
	@Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {

        auth.authenticationProvider(dbAuthenticationProvider);
        
    }
	
	@Override
    @Bean
    public AuthenticationManager authenticationManagerBean() throws Exception {
        return super.authenticationManagerBean();
    }
}


@Configuration
@Order(2)
public class AADSecurityConfig extends AADResourceServerWebSecurityConfigurerAdapter {
	
    @Override
    protected void configure(HttpSecurity http) throws Exception {
        super.configure(http);
        http.cors().configurationSource(corsConfigurationSource());
        
        http
        .authorizeRequests()
        .antMatchers(AUTH_WHITELIST).permitAll().and()
        .antMatcher("/oauth/**")
        .authorizeRequests((requests) -> requests.anyRequest().authenticated())
        .csrf().disable()
        .exceptionHandling()
        	.authenticationEntryPoint(authenticationEntryPoint)
        	.accessDeniedHandler(accessDeniedHandler)
        .and()
        .sessionManagement()
        .sessionCreationPolicy(SessionCreationPolicy.STATELESS)
    
        ;   
    }
  
}

Thanks for the additional information. Just to confirm you are really using the 1.6 release as stated above?

I'm a bit confused because line numbers don't really match:
https://github.com/awslabs/aws-serverless-java-container/blob/aws-serverless-java-container-1.6/aws-serverless-java-container-core/src/main/java/com/amazonaws/serverless/proxy/internal/servlet/AwsProxyHttpServletRequest.java#L340

[karpagamvijayan]

Yes @deki I have used 1.6 version
PFB the updated logs.

any help please?

[deki]

@karpagamvijayan I tried to reproduce the issue as described but the class you pasted doesn't work: package com.sample.karpagam.vijayan.security does not exist

Would it be possible for you to provide a repo that I can just clone?
