Describe the problem/error/question

When I want to test a MQTT Trigger Node by clicking on the button “Listen for Event” the workflow hangs. It cannot be stopped, nor does it respect any timeout limits set.

What is the error message (if any)?

I have not forgotten about this, I was going to check it today but ran out of time so this will be the first thing I look at tomorrow morning.

Hey @bees8,

It is currently wating to be picked up, It looks like the node needs a few changes not just this one so they may be handled at once.

Thanks Jon. I restarted the instance and just let it trigger with a production flow.

works perfectly, got triggered about 91,000 times for the past 48 hours :wink: https://hashscan.io/testnet/topic/0.0.3124619
