Request to https://undefined/

[j2ghz]

I set up the Env vars, next config and react component according to the readme, and I'm seeing the browser make a request to https://undefined/simple/simple.gif?version=custom_proxy_11&hostname=... (and fail).

I tried to see where the undefined could be coming from, but I only got as far as your minified proxy.js.

Hi Jozef,

The URL is constructed using the SIMPLE_ANALYTICS_HOSTNAME variable (see the code below), so this means that this variable is somehow undefined.

Could you double check whether there are no typos?

And if you are use Turborepo and deploying to Vercel, make sure you add the variables to turbo.json.

Let me know whether this solves anything for you.

export function withSimpleAnalytics(
  nextConfig: NextConfig,
  options?: WithSimpleAnalyticsOptions,
): NextConfig {
  const hostname = options?.hostname ?? process.env.SIMPLE_ANALYTICS_HOSTNAME;

  const clientHints = buildClientHintHeaders(options?.clientHints);

  const nextAnalyticsConfig: NextConfig = {
    async rewrites() {
      const existingRewrites = await nextConfig.rewrites?.();

      const rewrites = [
        {
          source: "/proxy.js",
          destination: `https://simpleanalyticsexternal.com/proxy.js?hostname=${hostname}&path=/simple`,
