🐛 BUG: Regression with console.log-ing objects

[Cherry]

Which Cloudflare product(s) does this pertain to?

Wrangler

What version of Wrangler are you using?

3.2.0

What operating system are you using?

Windows

Describe the Bug

Deep objects are no longer logged as previously. While not the best method of debugging, logging objects is still very useful for quick debug.

Basic Example

With the following script as worker.ts:

export default {
	fetch() {
		console.log({
			foo: {
				bar: {
					baz: true
				}
			}
		})
		return new Response('ok');
	}
}

wrangler 2

• npx wrangler@2.20.0 dev --local worker.ts

GET / 200 OK (43.86ms)
{ foo: { bar: { baz: true } } }

wrangler 3

• npx wrangler@3.2.0 dev worker.ts

[mf:inf] GET /favicon.ico 200 OK (1ms)
Object {
  foo: Object
}

Deeper example

In Node.js, object properties do begin to get truncated when logging deep objects, such as with this script:

export default {
	fetch() {
		console.log({
			foo: {
				bar: {
					baz: {
						foo: {
							bar: true
						}
					}
				}
			}
		})
		return new Response('ok');
	}
}

wrangler 2 output:

{ foo: { bar: { baz: [Object] } } }

wrangler 3 output:

Object {
  foo: Object
}

In node.js, the common way to solve this is using console.dir(..., {depth: null}), so when updating the script to the following:

export default {
	fetch() {
		console.dir({
			foo: {
				bar: {
					baz: {
						foo: {
							bar: true
						}
					}
				}
			}
		}, {depth: null})
		return new Response('ok');
	}
}

wrangler 2 output:

{
  foo: {
    bar: { baz: { foo: { bar: true } } }
  }
}

wrangler 3 output:

[ 'Object', '{\n  foo: Object\n}', 'Object', '{\n  depth: null\n}' ]

@mrbbot Is this related to how Miniflare handles logging with WorkerD?

Is there any updates on this issue? Its been months since any updates have been given and its still a major issue when developing locally with Wrangler.

@Cherry thanks for filing this issue. This is definitely something we need to fix. We're going to pick this up shortly and hopefully have a resolution sometime in the next couple of weeks.

cloudflare/workerd#1294 has now been merged, so this should be fixed in next week's Wrangler release 👍

EDIT: My initial comment here was looking at the wrong thing, sorry!

This appears to be resolved now with 3.15.0, going to mark this as resolved! 🥳Thank you for the fix!
