Example CI Not Working

[holgerd77]

The latest EIP-7702 examples contribution at #4015 show, that the examples CI job is not working on a fundamental level, so the examples are (at the state of reviewing, 35a1620 as latest commit still broken at the TypeScript level (using VM.create()), see this job run e.g.:

At the same time the examples CI goes through and showing green:

This is a very urgent fix, I would not dare to release before we have this settled, since it could point to fundamentional flaws in our API if examples are not working.

Beyond the above case there seems to be other non-working example cases - taken from a quick scrolling through the CL output - e.g. in MPT, likely others.

This is likely because the examples in that PR do main().catch(console.error). If main() throws (and there is no catch) then the file itself will throw. But, if it is written as main().catch(console.error) then any error is caught and written to console.error, and the error itself is not re-thrown. So in that case, if there is an error in main() it will (likely) not fail the CI.

Would still need verification if my claim above is correct though!

Yes, just checked, this run fails: https://github.com/ethereumjs/ethereumjs-monorepo/actions/runs/14640684048/job/41082190031?pr=4015 after this commit: 9b3dc63

Ok, thanks! 🙂

So, solved by Jochems investigations. Will close.
