React-devtools: Started to crash quite recently with a "Uncaught TypeError: Cannot read property 'replace' of null" error

This is happening to me in Electron when devtools 3.4.0 open. (UI is "Waiting for roots to load").

Got this in the Chrome extension initially after upgrading to [email protected] from 16.3, but resolved by disabling the extension and re-enabling. ¯\_(ツ)_/¯

I had this bug on my macbook but not on windows pc. Then I updated React to 16.6 and got the same bug on win too :(

I fixed this issue removing the electron-react-devtools. I was using both electron-react-devtools and react-developer-tools.

Edit: I also removed the extensions folder and DevTools Extensions file from ~/.config/Electron.

I am getting the same issue in React Native with React 16.6

I had the same issue. I was able to fix it only by deleting the extensions folder. In my case (Windows):
C:\Users\{USERNAME}\AppData\Roaming\Electron

Other platforms:

$XDG_CONFIG_HOME or ~/.config on Linux
~/Library/Application Support on macOS

I solved this issue on React Native by updating react-devtools-core to 3.6.1, steps:

navigate to ./node_modules/react-native
open package.json and update react-devtools-core to 3.6.1
run yarn install or npm install

it should work 👍

React DevTools has been rewritten and recently launched a new version 4 UI. The source code for this rewrite was done in a separate repository and now lives in the main React repo (github.com/facebook/react).

Because version 4 was a total rewrite, and all issues in this repository are related to the old version 3 of the extension, I am closing all issues in this repository. If you can still reproduce this issue, or believe this feature request is still relevant, please open a new issue in the React repo: https://github.com/facebook/react/issues/new?labels=Component:%20Developer%20Tools
