I’m using docker-compose from kafka-connect-zeebe following the the install guide. mvn clean install -DskipTests worked fine. However, when I try to run docker-compose up the connect service doesn’t start properly and I’m getting an empty response from the server when running any command like this: curl localhost:8083/
Here are some logs which may help:
