Greetings...

I just updated my Node-Red Addon in Home Assistant to 14.5.0 (Latest update prompt as of 10/2/23). The change log states: "Ships with Node-RED v3.1". I am now getting an error that I can't seem to identify the source. Perhaps I'm glossing over it, but the error message doesn't point to a Node name/ID.

The error references Node-Red 4.0, which I find interesting because both the Home Assistant Addon and the Node-Red hamburger dropdown in the right hand corner both state version 3.1. So I don't quite understand the Deprecated API reference to v4.0.

The error does reference `node-red-contrib-home-assistant-websocket`. If this is related to the Home Assistant Websocket, what is the reference to the deprecated API in v4.0 requiring a CallBack when I'm not running 4.0 but rather v3.1?

Thank you all very much

It is a warning and clearly states, as of node red 4.0 `RED.util.evaluateJSONataExpression` will require a callback.

You can ignore it till node-red 4 is released, as of then if HA has not updated the node to use async with a call back your HA nodes that use the RED.util function will stop working.

If I was you I would raise this with the HA node Athor/s.

There are several threads: [Search results for 'Deprecated evaluateJSONataExpression ' - Node-RED Forum](https://discourse.nodered.org/search?q=Deprecated%20evaluateJSONataExpression%20)

As far as I know, HA have been informed.

Quick search on google for `"HA depreciated evaluateJSONataExpression"` reveals:
