(node:29044) electron: Failed to load URL: chrome-extension://idfgllamndddgpeogaeoaiekkiafajcb/main.html with error: ERR_BLOCKED_BY_CLIENT
(Use `electron --trace-warnings ...` to show where the warning was created)
[29044:0818/105032.720:ERROR:CONSOLE(1)] "Ignoring unauthorized client request from null", source: devtools://devtools/bundled/models/extensions/extensions.js (1)

I’m not really sure what the issue is here, and since I’m using Electron Forge I can’t pass trace-warnings to electron. 😦

Is this an incorrect usage of electron-devtools-installer?

app.on('ready', async () => {
	if (process.env.NODE_ENV === 'development') {
		await install(REACT_DEVELOPER_TOOLS)
	}

	createWindow()
})

Removing the await install(...) line causes the error to go away, and logging the output of it just prints React Developer Tools, as if the install was successful.

The problem was that I was using a custom session. Since react-devtools-installer doesn’t let you choose the session, the custom session wasn’t getting the devtools.

Solution was to unset session and partition in webpreferences
