Save block not available in MQTT_Response

[felixbohnus]

Hi
I tried to subscribe to a specific topic and publish a message depending on the received massage:

test_name: Receive and publish message

paho-mqtt:
  !include ../shared/mqtt.config.yaml

stages:
  - name: publish example message and wait for response
    mqtt_publish:
      topic: playground/publish
      json:
        msg: msg
    mqtt_response:
      topic: playground/receive
      save:
        json:
          saved_msg: msg
      timeout: 60
  - name: publish received message
    mqtt_publish:
      topic: playground/publish_received_msg
      json:
        msg: "{saved_msg}"

Then I get the following error:

E           tavern._core.exceptions.BadSchemaError:
E           ---
E
E           {'topic': 'playground/receive', 'save': {'json': {'saved_msg': 'msg'}}, 'timeout': 60} is not valid under any of the given schemas
E           test\integration\playground.tavern.yaml: line 9-19:

E                 save:
E                   json:

E             - name: publish received message
E               mqtt_publish:

It is also not defined in the YAML-schema defining the tests:
https://github.com/taverntesting/tavern/blob/4396844435a74d0af4c06ca64eb1c15cf02b61ab/tavern/_core/schema/tests.jsonschema.yaml

So the question is: Is there another way to save and access variables from mqtt-responses?

This used to work in Tavern 1.x but it seems like I accidentally broke it in the 2.0 release. I'll look at fixing it within the next few days but if you need this for the time being you may need to keep using tavern>=1,<2

Works now, thank you for fixing it!
