SyntaxError: Non-default export is not supported in main.js:20

[duffn]

Hello,
Thank you for the nice starter. I'm attempting to run the project and after having installed dependencies and building, receive this error when running npm run start.
Thanks for any help.

export { index as default };

What exactly don’t you understand on the error message: SyntaxError: Non-default export is not supported in main.js:20?
It’s even mentioned in src/index.ts.

EDIT: Aha, I see now, you just built the example and it produces export { index as default };.

[duffn]

The starter is meant to generate a non-working project per the README instructions? All I've done is clone the project and attempt to run it per the README.

EDIT: Yes, I've only built the example.

[jirutka]

No, it’s not. I misunderstood your report. Sorry about it.

This regression is caused by changes in rollup 2.55.0, specifically #4182.
