ServletContext: Servlet.getServletConfig() is null

Serverless Java Container version: 2.0.0
Implementations: Spring Boot 3
Framework version: SpringBoot3.0.6
Frontend service: API GATEWAY using SpringBootLambdaContainerHandler
Deployment method: eg Cloudformation (using CDK)
Scenario
I want to retrieve header information from API Gateway (authorizer) to my Springboot application.
Expected behavior
I would expect that I would be able to fetch some information (e.g. CognitoIdentity) by adding a filter on startup of the SpringBootLambdaContainerHandler would work
Actual behavior
Error is raised as java.lang.NullPointerException: Cannot invoke "jakarta.servlet.ServletConfig.getServletName()" because the return value of "jakarta.servlet.Servlet.getServletConfig()" is null
Steps to reproduce
I'm following the example of Pet Store from serverless/sample/springboot3
running from a local lambda.
FROM gradle:7-jdk17-alpine AS build
COPY --chown=gradle:gradle . /home/gradle/src
WORKDIR /home/gradle/src
RUN gradle build -x test --no-daemon
FROM openjdk:17-jdk-alpine as local
EXPOSE 8080
RUN mkdir /app
WORKDIR /app
COPY . /app
COPY --from=build /home/gradle/src/build/libs/*.jar /app/myapp.jar
CMD ["java", "-jar","/app/myapp.jar"]
FROM public.ecr.aws/lambda/java:21 AS lambda
# Copy function code and runtime dependencies from Gradle layout
COPY --from=build /home/gradle/src/build/classes/kotlin/main ${LAMBDA_TASK_ROOT}
COPY --from=build /home/gradle/src/build/dependency/* ${LAMBDA_TASK_ROOT}/lib/
COPY --from=build /home/gradle/src/build/resources/main/* ${LAMBDA_TASK_ROOT}
CMD [ "StreamLambdaHandler::handleRequest"]class StreamLambdaHandler : RequestStreamHandler {
init {
// we enable the timer for debugging. This SHOULD NOT be enabled in production.
Timer.enable()
}
@Throws(IOException::class)
override fun handleRequest(inputStream: InputStream, outputStream: OutputStream, context: Context) {
handler!!.proxyStream(inputStream, outputStream, context)
}
companion object {
private var handler: SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse>? = null
init {
try {
handler = SpringBootLambdaContainerHandler.getAwsProxyHandler(ApiApplication::class.java)
// we use the onStartup method of the handler to register our custom filter
(handler as SpringBootLambdaContainerHandler<AwsProxyRequest, AwsProxyResponse>?)?.onStartup { servletContext: ServletContext ->
val registration = servletContext.addFilter(
"CognitoIdentityFilter",
CognitoIdentityFilter::class.java
)
registration.addMappingForUrlPatterns(
EnumSet.of(DispatcherType.REQUEST),
true,
"/*"
)
}
} catch (e: ContainerInitializationException) {
// if we fail here. We re-throw the exception to force another cold start
e.printStackTrace()
throw RuntimeException("Could not initialize Spring Boot application", e)
}
}
}
}Full log output

I managed to solve this by removing WebFlux from my gradle setup.
