2 years ago I'm not sure if its the problem but there is mismatch in parameter types. In the definition of demo_kafka_chain_meta you state it has a parameter called triggers which is of type "string".
But you are attempting in the rule to pass {{ trigger }} - but trigger is an object - not a string. If you want to pass the whole trigger then you will need to use an object type.
I always try and use orquesta rather than action-chains, so in this type of scenario I usually define the action as an orquesta workflow with a parameter of type object, and then would pass in something like {{trigger.body}}. So I'm not sure if there is a special problem with using {{trigger}} and action-chains.

I have stackstorm configured in Ubuntu VM. And I'm integrating stackstorm with alert-manager for alert auto remediation. I'm getting the below error while executing the actionchain.
Error:
