Subscribing to a topic returns nothing

[ThePersistentTester]

I'm new to RobotFramework and (#mqtt )MQTT. The main requirement for the broker is that only a valid JSON message should be published. So far I've been able to successfully publish my messages. I subscribe to the topic I posted to in PowerShell and I see that the message has been posted.

However, When I try to subscribe and validate, in RIDE, I dont get any message returned.

E.g: I was able to publish this as a retained message to the topic:

Test/TestTopic {"schema": { "name": "XkvPYD2i", "version": 1 },"title": "XkvPYD2i","tags": "XkvPYD2i"} This code works:

Publish Single ${topic} ${message} ${qos} ${Retained} ${broker.uri} (Where the global file defines these values( as above) ${qos}=0) This code doesn't work

@{messages}= Subscribe ${topic} qos=${qos} timeout=5 limit=0 log ${messages} I expect to have the message (I posted above) returned and stored in ${messages}. But I get the following(from logs):

KEYWORD BuiltIn. Log ${messages} Documentation: Logs the given message with the given level.

Start / End / Elapsed: 20190219 14:57:53.909 / 20190219 14:57:53.910 / 00:00:00.001 14:57:53.910 INFO [] 20190219 14:57:53.907 : INFO : @{messages} = [ ] 20190219 14:57:53.910 : INFO : [] Can anyone advise how can I make that work? Thanks!

This is no longer an issue
