"Extension server error: Operation failed: Permission denied"

[b-smiley]

Electron app appears to be waiting for flask. Cannot get to the main page of the starter code.

Error Messages (They just kept repeating until I Ctrl+C)

Steps to Reproduce

Steps to reproduce the behavior:

1. Followed the getting started guide
2. Git cloned, using Git bash
3. pip3 install -r requirements.txt
4. yarn install
5. yarn run start

Expected behavior

I expect the main boilerplate app to load.

Screenshots

Additional context

I set the Firewall on windows to allow both private and public networks, or either or. The issue persists in all scenarios

I've been using this template successfully for a while now. For some unknown reason I'm also getting these messages when trying to start my app, except I'm using Node.js v18.16.1.

have the same issue on mac

[huangzhii]

The error message you're encountering ERR_OSSL_EVP_UNSUPPORTED is a common issue when using Node.js version 17 or newer with certain tools or dependencies that rely on OpenSSL for cryptographic functions.

My solution is to change the Node.js version. You can use a version manager such as nvm (Node Version Manager) for Unix-based systems (Linux, macOS) or nvm-windows for Windows. Here's how you would use nvm to switch to Node.js version 16:

nvm install 16
nvm use 16

After that, make sure to either close and reopen your terminal for the nvm command to become available, or you can source your profile file with a command like source ~/.zshrc (the file may vary based on your shell).

When open a new terminal, run nvm use 16 again.

Then this issue will be disappear.

Lines 33 to 35 in c78c0d0

	// Start & identify React & Electron processes
	spawn('cross-env BROWSER=none react-scripts start', spawnOptions.showLogs);
	spawn('electron .', spawnOptions.showLogs);

Another solution is to start the development script with the legacy ssl mode on line 34

spawn('cross-env BROWSER=none NODE_OPTIONS=--openssl-legacy-provider react-scripts start', spawnOptions.showLogs);
