When working with Node.js, you might encounter an error message like:

NodeError [SystemError]: A system error occurred: uv_interface_addresses returned Unknown system error 13

This message indicates that a system error occurred when Node.js attempted to access network information using the uv_interface_addresses function. The issue is often related to permission problems or network configuration issues on your operating system.

Common Causes

Some common reasons for this error include:

Permission Issues: Node.js might not have the required permissions to access network information. This can happen if the application runs with limited privileges.
Network Configuration Issues: Your OS's network settings might prevent uv_interface_addresses from retrieving the necessary information.
Node.js or OS Version Issues: Some versions of Node.js or your OS may have bugs or changes affecting this function.

Recommended Fix

To fix this issue in a Next.js project, modify node_modules/next/dist/lib/get-network-host.js by replacing certain parts of its contents with the following code:

node_modules/next/dist/lib/get-network-host.js

"use strict";
Object.defineProperty(exports, "__esModule", {
    value: true
});
Object.defineProperty(exports, "getNetworkHost", {
    enumerable: true,
    get: function () {
        return getNetworkHost;
    }
});

const _os = /*#__PURE__*/ _interop_require_default(require("os"));

function _interop_require_default(obj) {
    return obj && obj.__esModule ? obj : {
        default: obj
    };
}

// Patched version
function getNetworkHosts(family) {
    let interfaces;

    try {
        interfaces = _os.default.networkInterfaces();
    } catch (err) {
        // fallback kalau access network gagal
        return family === "IPv4" ? ["127.0.0.1"] : [];
    }

    const hosts = [];
    if (!interfaces) {
        return family === "IPv4" ? ["127.0.0.1"] : [];
    }

    Object.keys(interfaces).forEach((key) => {
        interfaces[key]?.filter((networkInterface) => {
            switch (networkInterface.family) {
                case 'IPv6':
                    return family === 'IPv6' &&
                        networkInterface.scopeid === 0 &&
                        networkInterface.address !== '::1';
                case 'IPv4':
                    return family === 'IPv4' &&
                        networkInterface.address !== '127.0.0.1';
                default:
                    return false;
            }
        }).forEach((networkInterface) => {
            if (networkInterface.address) {
                hosts.push(networkInterface.address);
            }
        });
    });

    // kalau gagal dapet apa-apa → fallback
    if (!hosts.length && family === "IPv4") {
        return ["127.0.0.1"];
    }

    return hosts;
}

function getNetworkHost(family) {
    const hosts = getNetworkHosts(family);
    return hosts[0] ?? null;
}

//# sourceMappingURL=get-network-host.js.map

This fix ensures that if network interfaces cannot be retrieved, the function will fail gracefully without breaking the app.

Since modifying node_modules is not a permanent solution, consider implementing a patching mechanism (e.g., using patch-package) or overriding the function at runtime.

By applying this fix, you should be able to resolve the uv_interface_addresses error and continue working with Next.js without issues.
