No Simple Example Exists

All these examples are too complicated, brittle, and fragile. Can someone please give the most simple working example possible with only two files

1. main.kt
2. script.kts

When I try to run the simple example I get

: wrong number of arguments: 0 expected: 1: java.lang.IllegalArgumentException: wrong number of arguments: 0 expected: 1

Start by reviewing the existing examples and the two requested entry files, main.kt and script.kts. Reproduce the reported wrong-number-of-arguments error with the simplest available setup, then document a working two-file example whose execution no longer produces that error.
