Issue with OpenCTI Platform container

[mattheff2]

When running the docker-compose command, all containers start up and run except for the final platform container. Error message is below:

I had a similar problem in the last version, I managed to solve it by deleting the old rabbitmq volume 'docker volume rm docker_amqpdata' and rebuilding the container. This was just my workaround and may not solve your problem specifically, even with the same error output as mine.
