In this line "const provider = new ethers.providers.JsonRpcProvider" remove the ".providers" thing. Patrick did updated this in his repo

The error Error: could not detect network (event="noNetwork", code=NETWORK_ERROR, version=providers/5.6.0) typically occurs when the Ethereum node (in this case, the local node running at http://127.0.0.1:7545) is not running or is not accessible.

Here are a few steps you can take to troubleshoot this issue:

1. Check if the local Ethereum node is running: Before running the deploy.js script, ensure that you have started the local Ethereum node at http://127.0.0.1:7545. If you're using a tool like Ganache, make sure it's running and listening on the correct port.

2. Verify the URL: Double-check the URL you're using to connect to the local Ethereum node. In your code, it's "http://127.0.0.1:7545". Make sure this URL is correct and matches the endpoint where your local node is running.

3. Check for network connectivity: Ensure that your application can connect to the specified URL. You can try pinging the URL from the command line or using a tool like curl to verify network connectivity.

4. Check for firewall or proxy settings: If you're running your application on a machine with a firewall or behind a proxy, make sure that the necessary network connections are allowed.

5. Try different provider options: If the issue persists, you can try using a different provider or a different way to instantiate the provider. For example, you can try using the WebSocketProvider instead of the JsonRpcProvider:

const provider = new ethers.providers.WebSocketProvider("ws://127.0.0.1:8545");

Make sure to replace the URL with the appropriate WebSocket URL for your local node.

6. Check the Ethereum node logs: If you're still having trouble, check the logs of your local Ethereum node for any error messages or additional information that could help diagnose the issue.

If the issue persists after trying these steps, please provide more information about your setup, such as the tool you're using to run the local Ethereum node (e.g., Ganache, Hardhat, Truffle), and any relevant configuration details.
