Hello, Sprykees. I have totally weird behavior in my publish listeners. I'm still using Spryker

202009.0

. Previously everything was fine. My last task was to extend

product-discontinued

module to have store relation so product can be discontinued for one store only. As I introduced new

spy_product_discontinued_store

table, I created two new listeners, that publish or unpublish when there are changes in this store. This listeners doesn't extend core listeners. Locally everything work perfectly, but on staging it works time-to-time. Once it works, next time it fails with an error:

"errorMessage":"Message body is not valid"

. If I trigger listeners with

console event:trigger:listener

I have no problem, everything works fine. I have found this message in

EventQueueConsumer

and we have it, when listener or

EventEntityTransfer

is missing. But, as I see in rabbitMQ message, both

listenerClassName

and

transferClassName

are set and they definitely exist. And, as I said previously, it works randomly - sometimes works, sometimes - not. I have no idea how to debug it or what else I can do. Any ideas? Thank you in advance.

I think we had something like this before. MEssages looked fine in rabbitmq UI but when the consumer received them, the message body was empty. I actually found this by connecting my local instance to staging / production rabbitmq and then use xdebug. If I remember correctly, Restarting rabbitmq solved this, but we never found the root issue

Can you advice me how to debug it? I've found only how to debug listeners.

first you have to find the rabbitmq connection settings, and replace them with the ones of the staging instance. you find the correct settings in AWS -> Systems Manager -> Parameter Store and search for BROKER_

Thank you, David, I'll try it.
