I could have an explanation for what you see:

> <https://github.com/node-red/node-red/blob/a55554193bac2ee4997948c6a15dd752844cace4/packages/node_modules/%40node-red/nodes/core/function/10-function.js#L316-L323>

After the function node imported an _ExternalModule_ as `lib`, it references (line 318) `lib.default` to the variable name defined on the property editor.

`lib.default` yet is only present if the module has defined an `export default` or `export { ..., ... as default, ...}`.

`javascript-interface-library` doesn't define an `export default`, but _only_ `export { ... }`.

Is this a bug of Node-RED? I'm not sure...
