Debezium won't run

[marcuslwh]

Class io.confluent.connect.avro.AvroConverter could not be found

Good afternoon, can you tell me which docker compose you’re running? And also the specifications of your machine. Thank you

Hi Alfredo, thank you so much for your response!

I am running the one for mysql to neo4j. After doing docker compose up -d, all the containers run except debezium, the logs says that Class io.confluent.connect.avro.AvroConverter could not be found. I am using windows 11, 64GB ram.

Can you try to refresh the by running:
docker-compose down -v
docker-compose up -d

This because sometimes happens the distribution can have some problems downloading the Avro-converter plugin, I will try to fix it by adding directly the Avro-converter in the docker-compose startup script

Hi Alfredo,

Refreshing it doesn't help. Yes, the issue is with the avro converter plugin. I managed to install the relevant JAR files from the confluent maven repository into the plugin directory and the debezium container is now running. Adding the avro convertor into the docker-compose startup script would certainly help.

I also needed to add a topic prefix in the connector configuration. After doing so, however, the debezium connector doesn't seem to be successfully sending the messages to the kafka instance.

If there is any chance at all you could look into the things that need to be fixed in the codes you have provided for this tutorial to work, it would be amazing. Thank you so much for this tutorial, it is definitely very helpful.
