Spring Boot running on Docker Kafka Issue

I have a problem to send a request from account-cmd and fetch it from account-query with database in Spring Boot through Kafka. I think there can be a problem in Kafka but I couldn't find where the issue is. I updated my repo again but I can successfully send a request and insert the data in Mongodb but I couldn't see any data in MySQL. Here are some screenshots shown below. How can I fix it? I hope you can help me. Here is the link : https://github.com/Rapter1990/cqrs-example
