I had same issue, and follow but still not working, could you help me?
Are you on 2.3.3 as well? I had the same issue yesterday! Couldn't find a resolution. It almost seems as though I *have* to have RabbitMQ installed to use Bulk API?
You sure that disabling that module actually fixes this?
Disabled, still getting error.
You need to install rabbitmq.
On debian run:
sudo apt-get update && sudo apt-get install rabbitmq-server
I tried, but still i'm getting "The order confirmation email is not sent".
