I get this every time I start Node-RED. I cant delete this node because it says it's in use but it's not in any active flow. How do I stop this?
Thanks 🙂
## 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.

You can't delete the _module_ because you must have a ThingSpeak node somewhere in your flows.
Have you searched for it (Ctrl-F in the editor)? It could be a configuration node - open up the config node sidebar to see if its listed there.
