When I am trying to use the following node:

> **[node-red-contrib-harmony-extra](https://flows.nodered.org/node/node-red-contrib-harmony-extra)**
>
> Harmony integration for Node-RED

I get the following error msg:

```auto
4 Jan 21:28:41 - [red] Uncaught Exception:
4 Jan 21:28:41 - [error] TypeError: Cannot read properties of undefined (reading 'getActivities')
    at /home/Wurmi/.node-red/node_modules/node-red-contrib-harmony-extra/harmony/harmony-server.js:112:19
    at process.processTicksAndRejections (node:internal/process/task_queues:95:5)
nodered.service: Main process exited, code=exited, status=1/FAILURE
nodered.service: Failed with result 'exit-code'.
nodered.service: Consumed 14.787s CPU time.

```

Nodered restarts after a frew seconds, but when i try to configure a node, the error appears again an nodered crashes again.

Some ideas?  
Thanks for help!

If you go to the node details using the link you posted, then click the link to go to its github page you will find that the page no longer exists. That suggests the node has been abandoned. I think you will have to look for an alternative solution.

Use the [harmony-websocket](https://flows.nodered.org/node/node-red-contrib-harmony-websocket) node instead, this works (using it myself)
