Failed to declare queue by RabbitMQ for Activiti Cloud Connector

saahilbhutwala — Tue, 12 Nov 2019 19:40:30 GMT

Hello, I am a Java developer working on creating a bpmn engine using Activiti deployed on a GKE Cluster. Currently, I have the cloud application set up and a runtime bundle with a bpmn process as well. With my cloud connector, I want it to interact with a job processing service and relay back the status once the job is finished. But after setting up everything I am encountering this error related to RabbitMQ queues that I cannot debug or am able to solve anywhere. I am new to rabbitMQ so any help would be highly appreciated please. Here is the error log :

this error I believe is the root cause of everything.

Any help is highly appreciated.

Thanks.
