Is there a required condition?\n\n100%\n\n### What is the expected behavior? Why is that the expected behavior?\n\nAll other files in the stack trace include a line number and offset. Ideally the faulting line should too (it's the one that humans are most interested in).\n\n### What do you see instead?\n\n\u003e Exception during run: SyntaxError[ @/broken-link-checker/test/00.internal.Link.js ]: Unexpected strict mode reserved word\n\n### Additional information\n\n```sh\ndocker run -it --entrypoint bash node\n```\n```sh\ngit init broken-link-checker\ncd broken-link-checker\ngit remote add origin https://github.com/jsoref/broken-link-checker/\ngit fetch origin 1a0bdd1e0b2159f939af4ec24aa8e0bd2382311f\ngit checkout FETCH_HEAD\nnpm install\nnpm run test\n```","author":{"url":"https://github.com/jsoref","@type":"Person","name":"jsoref"},"datePublished":"2026-01-12T00:34:01.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":0},"url":"https://github.com/61349/node/issues/61349"}
