How do I debug this? Package exists but package.json “exports” does not include entry for ...

I've started migrating a large application to Snowpack, but I am stuck at this message:

[17:31:25] [snowpack] Package "ramda" exists but package.json "exports" does not include entry for "./src/reject".

The issue is that, while this is a valid error indeed, I have no idea how to debug it. The docs do not show how to debug this and I tried running DEBUG=snowpack snowpack dev to no avail.

My next debugging effort would be to sprinkle console.log around in node_modules, which is not ideal.

Got any tips?

console.logging was no use, but grepping node_modules did the trick!

cd node_modules
grep ' from .ramda' . -r -n

Still curious about debugging options as this isn't ideal, so I'll leave it open for now.

The library that triggered the error uses commonjs like this:

require('ramda/src/forEach')

(The error being caused by ramda/src/reject in the previous post was due to me messing with pkg.exports for ramda to debug the issue)

which is perfectly valid with commonjs resolution. I added this to solve the problem:

import { nodeResolve } from '@rollup/plugin-node-resolve'

export default {
  // ...
  packageOptions: {
    rollup: {
      plugins: [nodeResolve()],
    },
  },
  // ...
}

That did not work, so I'm still not sure how to solve the problem.

This would have been a nicer error to debug.
