Currently, when attw fails, the error message may look something like,

A require call resolved to an ESM JavaScript file, which is an error in Node and some bundlers. CommonJS consumers will need to use a dynamic import. https://github.com/arethetypeswrong/arethetypeswrong.github.io/blob/main/docs/problems/CJSResolvesToESM.md.

The immediate question that comes to mind is: where is the import causing the failure? It would save considerable time and add clarity to the error message if the location of the incorrect module import was logged.
