ERR_REQUIRE_ESM error on start-slicemachine due to incorrect node-fetch version

[angeloashmore]

Versions

• slice-machine-ui: 0.3.7
• node: 16.15.0

Reproduction

Run the following commands to create a reproduction.

npx create-next-app
cd app-name

# Install node-fetch v3 (this could also come from another dependency)
npm i node-fetch

npx @slicemachine/init

Steps to reproduce

Start the project created above.

npm run slicemachine

What is expected?

Slice Machine starts.

What is actually happening?

[nix-shell:~]$ npm run slicemachine

> prismic-toolbar-issue-66-repro@0.1.0 slicemachine
> start-slicemachine


Launching server...

[slice-machine] /[path-to-project]/node_modules/slice-machine-ui/build/server/src/index.js:141

Error [ERR_REQUIRE_ESM]: require() of ES Module /[path-to-project]/node_modules/node-fetch/src/index.js from /[path-to-project]/node_modules/slice-machine-ui/build/server/src/index.js not supported.
Instead change the require of /[path-to-project]/node_modules/node-fetch/src/index.js in /[path-to-project]/node_modules/slice-machine-ui/build/server/src/index.js to a dynamic import() which is available in all CommonJS modules.

    at Object.<anonymous> (/[path-to-project]/node_modules/slice-machine-ui/build/server/src/index.js:16:38) {
  code: 'ERR_REQUIRE_ESM'
}

This happens because slice-machine-ui does not list node-fetch@cjs as a dependency. It is listed in the monorepo's root package.json, which does not get copied to the published package.

Current workaround: install a CJS-compatible version of node-fetch into a project. This will conflict if the project actually needs the ESM version.

Running into the same issue, would be great if this got resolved

Same issue here

Confirming I am using node-fetch v3 which breaks while node-fetch 2.x works
As my project needs ESM version, I am stucked :)

Tested. No longer an issue with the latest version of Slice Machine (^0.4.2)
