Fix UnsupportedProtocolError

✅ Solution

The "UnsupportedProtocolError" in yarn often arises from outdated yarn versions or when yarn tries to access registries using unsupported protocols like `git+ssh`. Upgrade yarn to the latest version using `npm install -g yarn` or explicitly configure yarn to use `https` by setting the registry URL via `yarn config set registry https://registry.npmjs.org`. Also, inspect your `.yarnrc` file and dependencies' URLs for incorrect or git-based protocols and change these to `https`.
