1337864 - Can't save FB XHR netmonitor log as HAR

Status: NEW

(DevTools :: Netmonitor, defect, P3)

Description

[(no longer active)]

STR:

1. Go to https://www.facebook.com/livemap and watch a live video.
2. Open devtools, and watch the stream of XHRs pouring in.
3. Click on a line and select Copy All As HAR or Save All As HAR.

They both fail with errors like this in the browser console:

"Handler function threw an exception: TypeError: undefined has no properties

This comes from ThreadSafeDevtoolsUtils.js:80.
