René's URL Explorer Experiment

{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"`RangeError: Invalid string length` when logging a particular Error with `console.error`","articleBody":"### Version\n\nv26.3.1\n\n### Platform\n\n```text\nDarwin HQX-VGM7H2WVFG 25.5.0 Darwin Kernel Version 25.5.0: Mon Apr 27 20:41:06 PDT 2026; root:xnu-12377.121.6~2/RELEASE_ARM64_T6030 arm64 arm Darwin\n```\n\n### Subsystem\n\nutil\n\n### What steps will reproduce the bug?\n\n1. `npm install @formatjs/icu-messageformat-parser@3.5.11`.\n2. Save this script:\n```javascript\ntry {\n  require('@formatjs/icu-messageformat-parser').parse(\n    `{0, plural, one {#  ''אהבתי'''} two {# ''אהבתי'''} other {# ''אהבתי'''} }`,\n    { requiresOtherClause: true, ignoreTag: true, shouldParseSkeletons: false },\n  );\n} catch (err) {\n  console.error(err);\n}\n```\n3. Run it. Observe error in the title:\n```\nλ node foo.js\nnode:internal/util/inspect:1885\n    tempLine += ctx.stylize(nodeModule, 'module');\n                    ^\n\nRangeError: Invalid string length\n    at markNodeModules (node:internal/util/inspect:1885:21)\n    at formatError (node:internal/util/inspect:2019:18)\n    at formatRaw (node:internal/util/inspect:1362:14)\n    at formatValue (node:internal/util/inspect:1195:19)\n    at inspect (node:internal/util/inspect:409:10)\n    at formatWithOptionsInternal (node:internal/util/inspect:2917:40)\n    at formatWithOptions (node:internal/util/inspect:2779:10)\n    at console.value (node:internal/console/constructor:377:14)\n    at console.error (node:internal/console/constructor:444:61)\n    at Object.\u003canonymous\u003e (/Users/ikerins/web/foo.js:7:11)\n\nNode.js v26.3.1\n```\n\nI was not able to reduce the reproduction to not use the library, e.g. by manually constructing a SyntaxError with the same properties that it is producing: \nhttps://github.com/formatjs/formatjs/blob/2093ca683a08dd8ae0226085329e9811eca38791/packages/icu-messageformat-parser/index.ts#L49-L56\n\nI'm not sure why that doesn't work. Sorry.\n\n### How often does it reproduce? Is there a required condition?\n\nAlways reproduces with the above script. I could not narrow it down beyond that.\n\n### What is the expected behavior? Why is that the expected behavior?\n\n`console.error` does not throw.\n\n### What do you see instead?\n\n```\nλ node foo.js\nnode:internal/util/inspect:1885\n    tempLine += ctx.stylize(nodeModule, 'module');\n                    ^\n\nRangeError: Invalid string length\n    at markNodeModules (node:internal/util/inspect:1885:21)\n    at formatError (node:internal/util/inspect:2019:18)\n    at formatRaw (node:internal/util/inspect:1362:14)\n    at formatValue (node:internal/util/inspect:1195:19)\n    at inspect (node:internal/util/inspect:409:10)\n    at formatWithOptionsInternal (node:internal/util/inspect:2917:40)\n    at formatWithOptions (node:internal/util/inspect:2779:10)\n    at console.value (node:internal/console/constructor:377:14)\n    at console.error (node:internal/console/constructor:444:61)\n    at Object.\u003canonymous\u003e (/Users/ikerins/web/foo.js:7:11)\n\nNode.js v26.3.1\n```\n\n### Additional information\n\nThe SyntaxError being logged _looks_ like this, but just constructing one with these properties directly does not reproduce, for reasons unknown. This:\n```\n  console.log(err.message);\n  console.log(err.stack);\n  console.log(err.location);\n  console.log(err.originalMessage);\n```\nProduces:\n```\nEXPECT_ARGUMENT_CLOSING_BRACE\nSyntaxError: EXPECT_ARGUMENT_CLOSING_BRACE\n    at Module.parse (/Users/ikerins/web/node_modules/@formatjs/index.ts:50:19)\n    at Object.\u003canonymous\u003e (/Users/ikerins/web/foo.js:2:49)\n    at Module._compile (node:internal/modules/cjs/loader:1873:14)\n    at Object..js (node:internal/modules/cjs/loader:2013:10)\n    at Module.load (node:internal/modules/cjs/loader:1596:32)\n    at Module._load (node:internal/modules/cjs/loader:1398:12)\n    at wrapModuleLoad (node:internal/modules/cjs/loader:255:19)\n    at Module.executeUserEntryPoint [as runMain] (node:internal/modules/run_main:154:5)\n    at node:internal/main/run_main_module:33:47\n{\n  start: { offset: 57, line: 1, column: 58 },\n  end: { offset: 73, line: 1, column: 74 }\n}\n{0, plural, one {#  ''אהבתי'''} two {# ''אהבתי'''} other {# ''אהבתי'''} }\n```\n\nAlso, the offending `console.error` invocation hangs for a pretty long time before throwing. About 5-7s.","author":{"url":"https://github.com/isker","@type":"Person","name":"isker"},"datePublished":"2026-06-25T20:38:32.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":2},"url":"https://github.com/64136/node/issues/64136"}
