It is similar to this issue in the forums:

Reproduction:

git clone git@github.com:lume/lume.git
cd lume
git checkout meteor-issue-12952
npm run fresh # this checks out git submodules, installs dependencies, and links projects together
cd apps/website/ # this is the meteor app
npm start # runs meteor, causes error

This will cause the above error.

This is related to the ecmascript package. When I comment out the package in .meteor/packages, this error goes away, and the server runs fine (it has no import statements in it), but of course the client won't work.

I am able to work around the client not working by removing the few import statements and instead using Package.* to get dependencies in client/entry.ts (compiled to client/entry.js).

The rest of the client is plain vanilla ES modules located inside public/, so no issues with that code, its the browser handling everything at that point (nice!).

I've not had any luck getting native ES modules working yet here:

Sidenote, this problem is caused when projects in the reproduction's super module repo (similar to a monorepo, but I'm using git submodules to pull in all the packages) are symlinked together with Yarn. This error goes away when things are not symlinked.

TLDR: this might show a problem with isobuild and handling symlinked dependencies in node_modules.
