fix node export path

Fixes this error message below.

Why the error occurs is unknown and might be specific to nextjs. But, adding node to the export path fixes the issue.

LGTM, approval

I don't know why this would fail either, but if your fix works, let's run with it. Will release a new build in a moment.

Thanks!
