I used rabbitmq message queueing system in my module. It works perfectly at my local environment. But as I deploy it to live-host (which runs at platform.sh) i get error topic % is not defined.
I found which block renders this exception error and put it below.
\Magento\Framework\Communication\Config
It seems the app tries to get topic information with topic name but can not find it.
At my local env I put var_dump and exit after data variable and got the message below.
It seems at live host topic information can not be found.
Do you know from where this information is obtained. I examined the Communication/Config.php , it gets its data from \Magento\Framework\Config\DataInterface , which is implemented for local storage, i guess.
Do you have any solution for this problem ?
