I have a flow where I want to add 2 the Yield node to, the first one did want to be connected, were unresponsive to be placed and connected on the flow. Eventual it responded.
The second Yield I can not eve drag onto the flow.
I have tried other nodes like Yaml ,Delay and they all work.
pi@raspberrypi:~/.node-red $ node-red-start
Start Node-RED
Once Node-RED has started, point a browser at http://192.168.1.100:1880
On Pi Node-RED works better with the Firefox or Chrome browser
Use node-red-stop to stop Node-RED
Use node-red-start to start Node-RED again
Use node-red-log to view the recent log output
Use sudo systemctl enable nodered.service to autostart Node-RED at every boot
Use sudo systemctl disable nodered.service to disable autostart on boot
To find more nodes and example flows - go to http://flows.nodered.org
Starting as a systemd service.
Started Node-RED graphical event wiring tool.

---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

The Yield node -
This node sends messages passed from msg.payload separately down the flow. Simply puts the messages in an array and assign to msg.payload.
I've not used this yield node but it doesn't look too different to the built-in split node - if you can't get it working, you might want to look at that.
Ps, that yield node is over 4y old - might be abandoned. But you could raise an issue on its repo if you spot the issue.
