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.

Which error are you asking about?

  1. the error relating to the install of node-red-contrib-aedes/aedes-mqtt-broker.
  2. the error saying 'no such file or directory' relating to the path E:\sys\class\leds\led:run\brightness.

Rebuilding Node-RED from src won't do anything about either of those errors.

For the first error, you need to run npm rebuild node-red-contrib-aedes in your node-red user directory.

For the second error... you need to identify what node you have installed is causing that. It isn't a core node.

The problem is I don't really know how it's caused

5

I will try these solutions. Thank you

I think this is because I have two source codes running locally, I will continue to try to solve this problem tomorrow, thank you for your help
