{"@context":"https://schema.org","@type":"DiscussionForumPosting","headline":"util.inspect({level: \"info\"}) exits the debug session","articleBody":"When debugging in node.js 5.3.0 the script `bug.js`\n\n``` javascript\nvar util = require('util');\nutil.inspect({level: \"info \"});\nconsole.log(\"Test\");\n```\n\nwith `node debug bug.js`, the debugging session exits. I tried the same in node.js 4.2.4 and it doesn't. When debugging  the difference in `lib/util.js`, line 324 in 5.3.0 looks like this:\n\n``` javascript\nvar promiseInternals = inspectPromise(value);\n```\n\nand line 319 in 4.2.4 looks like:\n\n``` javascript\nvar promiseInternals = value instanceof Promise \u0026\u0026 inspectPromise(value);\n```\n\nAs value is not an instance of Promise, `inspectPromise(value)` is called in 5.3.0. Then `inspectPromise` calls `ensureDebugIsInitialized()` which on the other hand calls `require('vm').runInDebugContext('Debug')`. This causes the debugging session to exit. The issue was tested in Ubuntu 14.04 LTS.\n","author":{"url":"https://github.com/learnerbyheart","@type":"Person","name":"learnerbyheart"},"datePublished":"2015-12-27T20:14:59.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":43},"url":"https://github.com/4440/node/issues/4440"}
