Inputs not readable from code

A node whose inputs are the parameters of its code, such as a Script, has code they cannot be read from: it does not parse, it defines neither main nor transform, or its function takes parameters the node cannot connect. The draft is saved, but the workflow cannot run until the code is fixed.

What to do

Fix the code as the message says: correct the syntax, define main with one named parameter per input, or rename a parameter that is reserved.

Where it comes from

Checked before every run, for any node. It is one of the messages checks before a run.
