No Project Set Error (NO_PROJECT_SET)

This is a local development error that occurs when the Zuplo development server cannot load or find a valid project.

Common causes

• Build failure - The project fails to build, preventing the local development server from loading it. Check the terminal output for build errors.
• Invalid project structure - The project is missing required files such as routes.oas.json or package.json.
• Wrong working directory - The development server is started from a directory that does not contain a Zuplo project.
• Corrupted dependencies - The node_modules directory is missing or contains corrupted packages.

Steps to fix

1. Verify the terminal output for build errors and fix any reported issues.
2. Confirm the project directory contains the required Zuplo project files (routes.oas.json, package.json, and a modules directory).
3. Ensure the development server starts from the root of the Zuplo project directory.
4. Delete the node_modules directory and run npm install to reinstall dependencies.
5. Restart the local development server after making changes.
