When writing a custom code node in LS 5.0, the suggestions are not very smart.

For example, in LS for, if you want to get a normal vector you could type "system.normal" and it would suggest automatically "system.getSurfaceNormalWorldSpace".

In LS 5.0 that doesn't happen, you need to type the exact same thing as the API.

My suggestion is to make it a little bit smarter like it used to be in LS 5 ;)
