Hermes debugging using Chrome DevTools not working since 118.0.5993.70 update

[116-7]

Description

After having Chrome automatically update to 118.0.5993.70 on MacOS Hermes debugging using DevTools as described in the React Native documentation is no longer working.

Testing with Chrome Beta 119.0.6045.21 reveals same issue.

Google's release note for 118.0.5993.70 include mention of a change "CVE-2023-5475: Inappropriate implementation in DevTools." However, the link to Google's bugtracker is not public so it might not be related.

Workaround possible by installing previous version of Chrome for Testing - 117.0.5938.149 as per instructions on Chromium's website.

npx @puppeteer/browsers install chrome@117.0.5938.149

There was a recent Chromium update that appended "?for_tabs" to the /json/list request and due to the implementation of InspectorProxy in metro-inspector-proxy@0.76.8 which is included with the current RN 0.72 boilerplate app the entire url from the pathname rightwards is being compared to the path-only variables PAGES_LIST_JSON_URL, and PAGES_LIST_JSON_URL_2.

@116-7 well spotted! Note that the code for the inspector proxy has moved into the React Native repo. This is where we'd need to fix the routing logic:

react-native/packages/dev-middleware/src/inspector-proxy/InspectorProxy.js

Lines 97 to 100 in 3d5324a

	if (
	request.url === PAGES_LIST_JSON_URL ||
	request.url === PAGES_LIST_JSON_URL_2
	) {

Thanks @motiz88

Here is a PR #41005

Given this is affecting the current stable boilerplate version of RN (and possibly a lot of older versions) there may be hotfixes needed to the previous versions of metro-inspector-proxy as well.

It looks like Chrome is working on a fix on their side, which might be sufficient as far as old RN releases go: https://chromium-review.googlesource.com/c/chromium/src/+/4942670

Hi guys, I followed your lead and found this in Chrome's flag settings, changed it to disable and under the remote target RN will show again! Thanks and I hope this helps :)

Hi, where can I find this setting? I'm having this issue currently on RN 0.72.6 :/
