I am trying to use as source the RabbitMQ for Apache Pulsar. I run locally the binaries of Pulsar and I use the offical RabbitMQ connector. The RabbitMQ is running in server. For few moments can I see RabbitMQ dashboard that Pulsar is connect but the I get an error in Pulsar,

My yaml file for rabbitmq is,
configs:
host: "my.server"
port: 5672
virtualHost: "/"
username: "user"
password: "pass"
queueName: "topic"
connectionName: "my-connection"
requestedChannelMax: 0
Any ideas? Need to do something additional to my rabbitmq maybe?
I have seen that happen before sometimes with disk errors, sometimes with the wrong Java version. Make sure you are using the correct Java version for your version of Pulsar. Which version of Pulsar are you using? If it's the current github use JDK 17, otherwise probably JDK 8 or 11 are your best choice.
Is Pulsar running?
My config file
messaging protocol you need to comma delimit if you have multi
messagingProtocols=amqp
directory
protocolHandlerDirectory=./protocols
--- AMQP
add amqp configs
amqpListeners=amqp://127.0.0.1:5672 amqpTenant=public
