AWS Lambda timeout issue with spring boot application - spring

Question

I have a spring boot application which I am trying to deploy on AWS lambda .
I added StreamLambdaHandler as the handler class
public class StreamLambdaHandler implements RequestStreamHandler {
private static SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse> handler;
static {
try {
//handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(SituationalFlexibilityApp.class);
// For applications that take longer than 10 seconds to start, use the async builder:
handler = new SpringBootProxyHandlerBuilder<AwsProxyRequest>()
.defaultProxy()
.asyncInit()
.springBootApplication(SituationalFlexibilityApp.class)
.buildAndInitialize();
// we use the onStartup method of the handler to register our custom filter
handler.onStartup(servletContext -> {
FilterRegistration.Dynamic registration = servletContext.addFilter("CognitoIdentityFilter",CognitoIdentityFilter.class);
registration.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), true, "/*");
});
} catch (ContainerInitializationException e) {
// if we fail here. We re-throw the exception to force another cold start
e.printStackTrace();
throw new RuntimeException("Could not initialize Spring Boot application", e);
}
}
public StreamLambdaHandler() {
Timer.enable();
}
/*
* public StreamLambdaHandler() throws ContainerInitializationException {
*
* handler = new SpringBootProxyHandlerBuilder() .defaultProxy() .asyncInit()
* .springBootApplication(SlowApplication.class) .buildAndInitialize(); }
*/
#Override
public void handleRequest(InputStream input, OutputStream output, Context context) throws IOException {
handler.proxyStream(input, output, context);
}
When I test it on AWS lambda I get below exception
com.amazonaws.serverless.exceptions.ContainerInitializationException: Could not initialize framework within the 20000ms timeout
so I updated the lambda configuration for a timeout of 5 mins and added below line in the static block of the StreamLambdaHandler class
LambdaContainerHandler.getContainerConfig().setInitializationTimeout(2000000);
Now, I am seeing below exception
Exception in thread "Thread-0" java.lang.IllegalArgumentException: Could not find timer SPRINGBOOT2_COLD_START
Can someone please point me in the correct direction as I a noob in AWS services and lambda

Answer 1

I am not seeing this error after commenting out the below code in StreamLambdaHandler method
// Timer.enable();
