This looks like it could be related: https://stackoverflow.com/questions/69081410/error-err-require-esm-require-of-es-module-not-supported

Maybe it would be fixed if you added:

"module": true,

to the package.json?

Yeah, the issue is that Kanel is not (yet) ESM-ready. Sadly, it's not quite as easy as changing that one line, and making the change will affect everyone who is not setting "module": true in their package.json. I do intend to do something about this because I am facing issues with it myself, but I can't guarantee when.

If you want a hacky workaround, I know one friend who comments out the "module": true line in his package.json every time he runs Kanel and then undoes that afterwards. I know, not pretty, but it does work...

I ran into this issue for a project that uses "type": "module".

My workaround was to rename .kanelrc.js to .kanelrc.cjs, then override the config import:

kanel --config .kanelrc.cjs

Edit: this isn't necessary, because kanel automatically recognizes .kanelrc.cjs
