Hi, I have observed an issue with Node-RED "Data Layer Subscibe" node. In my case, the Node-RED is subscribing to a true/false condition from the datalayer and sending an update to cloud either when there is a change in condition or after every minute. The "Data Layer Subscribe" node didn't push the event during the change in specified variable state. Below are some of my observations regarding this issue. The "Data Layer Subscribe" node was not triggering an event even after the change in variable's true/false condition. Node-RED as an app was working well with other part of project. Such as periodically sending the updates of the same variable from datalayer using "Data Layer Request" node after every minute, etc. This issue is observed for the first time. From the past few days, neither ctrlX CORE nor Node-RED were restarted. May be there is some timeout issue with "Data Layer Subscribe" node? This error was cleared after I selected "Deploy" option in Node-RED. There was no change in the Node-RED program. I just moved a node to make the "Deploy" option visible for a fresh start. I'll check if the issue re-appears after few days. I am using Node-RED version 1.12.4+2.2.2-ctrlx. Please let me know if someone encounters the same issue. Many thanks
