Failed to load REACT_DEVELOPER_TOOLS with "allowFileAccess: true".

[sprout2000]

Overview

Since the React Devtools manifest version has moved to v3, I have been receiving the following error message:

(node:38604) ExtensionLoadWarning: Warnings loading extension at ${appdata}/extensions/fmkadmapgofadopljbjfkapdkoienihi:
  Permission 'scripting' is unknown or URL pattern is malformed.

Electron version

• Electron v22.0.0

How to reproduce

app.whenReady().then(() => {
  new BrowserWindow().loadFile("index.html");

  installExtension(REACT_DEVELOPER_TOOLS, {
    loadExtensionOptions: { allowFileAccess: true },
  });
});

Any word on this issue please?

This needs fixing upstream: facebook/react#25843

[simonbuchan]

Upstream punted and said Electron should implement manifest v3. There's a few people that put workarounds in there, though, perhaps one could be added as a stop-gap.
