As a beginner, to write server, I always see this but cannot find where is the uncaught error.

Will you add the line number [or error stack]to this error?

Thanks.

Does node --trace-warnings script.js work for you?

I think this should be an error, and definitely avoid in development, should not be a feature that open by start runtime with some flag.

A quick search would have led you to #12734. To summarize: it's under discussion but won't happen in the v8.x branch.

I'll go ahead and close this out. Your question has been answered and there isn't anything immediately actionable otherwise.
