I wrote a microservice infrastructure with Java Spring Boot. This infrastructure includes a discovery service, an API gateway and a microservice that sends messages to customers. In the meantime I have provided the microservices in Azure Kubernetes Service. All services are registered in the Discovery Service and for the routes I use the Cluster IP of the SendMessage Microservice.

application.properties

zuul.routes.contacts.path=/contacts/**
zuul.routes.contacts.url=http://10.0.205.4:8100

So far everything went well. After I started a request to my API gateway, a message was also sent. But now I get an error message even though I haven't made any changes. After I now start a request to send a message, I receive an error code of 500 Internal Server Error, but the message will still be sent.

{
    "timestamp": "2020-07-10T08:48:37.621+00:00",
    "status": 500,
    "error": "Internal Server Error",
    "message": ""
}

When I look at the logs from the API Gateway, it says the following:

2020-07-10 08:05:37.136  WARN 1 --- [nio-8800-exec-3] o.s.c.n.z.filters.post.SendErrorFilter   : Error during filtering
