Please read this post on sharing code on the forum: [How to share code or flow json](https://discourse.nodered.org/t/how-to-share-code-or-flow-json/506)

You can see at the top of the settings file it has `var i2c = require("i2c-bus");` - which is where it is trying to load the `i2c-bus` module. That is _not_ part of the default settings file.

...

I see @ukmoose has also replied - I echo his comments.
