Incorrect type attribute value in package.json?

[mholy-arbes]

The package.json contains the following type attribute value:
"type": "lib/index.d.ts"
According to the node.js documentation the correct value should be "commonjs" or the type attribute should not be present at all.

I'm mentioning this because it seems that when using cookies-next within a Next.js application that uses ES6 modules, the build fails if the type attribute does not have correct value.

Is this really an issue or am I mistaken? I´m new to the Node.js world.

Thank you.
