Bug

What is the current behavior?

1. Select a component
2. The right panel (property panel?) always shows Loading...
3. The following error is printed to the console.

backend.js:1 Uncaught TypeError: Cannot read property 'name' of undefined
    at O (backend.js:1)
    at s (backend.js:1)
    at s (backend.js:1)
    at l (backend.js:1)
    at Object.inspectElement (backend.js:6)
    at t.<anonymous> (backend.js:6)
    at t.r.emit (backend.js:6)
    at backend.js:32
    at t (backend.js:8)

I don't know why you minify the output, but the call stack points to here:

react/packages/react-devtools-shared/src/utils.js

Line 391 in f887d1a

} else if (data.constructor.name === 'ArrayBuffer') {

If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem. Your bug will get fixed much faster if we can run your code and it doesn't have dependencies other than React. Paste the link to your JSFiddle (https://jsfiddle.net/Luktwrdm/) or CodeSandbox (https://codesandbox.io/s/new) example below:

What is the expected behavior?

React DevTools displays the props of the selected component.

Which versions of React, and which browser / OS are affected by this issue? Did this work in previous versions of React?

React 16.12.0
Chrome 79.0.3945.88
IDK

Thanks for the repro case.

FYI this issue should be fixed in v4.4 (released today)

What is the release process like? I still see 4.3.0 on the Chrome web store: https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi

The release process is...the newer version will go live once Chrome reviews it. They seem to have fallen pretty far behind around the hoildays.
