Save as HAR file with content not working

[mezdej]

Save as HAR file with content is not working in dev tools.

In DebugView there is a log entry

[8740] [0918/094941.726:ERROR:CONSOLE(109)] "Uncaught (in promise) Error: Could not instantiate: ProductRegistryImpl.Registry", source: chrome-devtools://devtools/inspector.js (109)

How to make it work?

CEF 3.3112.1656.g9ec3e42
Chromium 60.0.3112.90
OS Windows
WebKit 537.36 (@e6ccc355a03184b2a4fa2b22bd15b89324d6a137)

Can you reproduce the issue with cefclient? When googling error I've found this: https://github.com/electron/electron/issues/12185 . It states that the issue reproduces in a specific scenario. What is your use case?

For me "Save as HAR file with content" does not work even in "cefsimple" (with added minimal code to show dev tools).

I have downloaded cef_binary_3.3497.1833.g13f506f_windows32_client and in cef client "Save as HAR file" is doing nothing...

This feature is not available in CEF devtools popup, however you can save it as HAR file by using remote debugging and a Google Chrome instance. Here are the steps:

1. In Google Chrome browser open "chrome://inspect" url and click "Open dedicated DevTools for Node"
2. Add "localhost:1234" connection and close the popup window
3. Run `cefclient --remote-debugging-port=1234` (it sets CefSettings.remote_debugging_port)
4. Refresh the "chrome://inspect" page in Google Chrome browser
5. You should see a new target on the Remote Target list. Click "inspect" link for this target and then follow the usual steps for saving as HAR file.
