I'm not sure if this fixes the linked issue. This comment says that we need to change tsconfig.dev.json, not tsconfig.json.

@Chriscbr actually it does. It does both. Look at the diff of the snap test. You'll need to click on the view file to see the scopes.

The same error occurs when the following commands

• npx projen new nextjs-ts --projenrc-ts
• yarn projen
  react-ts: Warning: To load an ES module, set "type": "module" in the package.json or use the .mjs extension #1463 (comment)

I tried these commands again and confirmed that the issue was fixed.
Thank you!
