Regression 2.4.x 2.5.x Unable to deploy to Elastic Beanstalk

[sdelamo]

Steps to reproduce

mn create-app example.micronaut.micronautguide --inplace

Health Endpoint

Add micronaut-management dependency:

dependencies {
...
..
.
    implementation("io.micronaut:micronaut-management")
}

Port 5000 EC2 Env

Create a file to run the application in port 5000 when deployed to Elastic Beanstalk

src/main/resources/application-ec2.yml

micronaut:
  server:
    port: 5000

Deployment

Generate a FAT JAR:

./gradlew build

Elastic Beanstalk application

Create a Java 11 application in Elastic Beanstalk.

As application code upload FAT JAR build/libs/micronautguide-0.1-all.jar.

Current behaviour

GET request to the health endpoint:

curl http://micronautguide.us-east-1.elasticbeanstalk.com/health 
{"message":"WebSocket Not Found","_links":{"self":{"href":"/health","templated":false}}}%   

Expected output

If I change the Micronaut version in gradle.properties to 2.4.4, generate and deploy the FAT JAR to Elastic Beanstalk

GET request to the health endpoint:

curl http://micronautguide.us-east-1.elasticbeanstalk.com/health 
{"status":"UP"}
