Reconnect to a uibuilder instance if node red is deployed

General

i am looking to reconnect to an open uibuilder instance automatically when a node red full deploy has taken place, is this possible? At present i have to refresh the instance for this to happen.

Any help would be appreciated as always .

Hi, this should already happen automatically. The client library instigates a running delay on disconnections. I never have to reload a page, it just works.

So if not working for you, we need to find out why. If you open your dev tools console on the browser showing the UI, you should see some output. You may need to up the logging level though which you can do from node-red or from front-end code.

Sorry work got in the way…. if i do a full deploy it dosent reconnect but any other deploy it does

This system was written entirely using AI if that may be an issue?

It shouldn't do, but AI generated code is notorious for hard-to-spot bugs.

Please check for errors or warnings appearing in the Node-RED log and do the same when viewing the page in your browser by opening the browser dev tools console.

Before proceding though, please let me know what version of node.js, Node-RED and UIBUILDER you are using - the easiest way to get that is to restart Node-RED and copy the lines from the start of the log to where is says Starting flows. e.g.:
