Hi @foggy stump. I'm kapa.ai, your friendly support bot. I will try to answer your question by searching through the knowledge base. :wave:

#

Based on the information in the knowledge sources, here are some key points and troubleshooting steps relevant to your issue:

1. Environment Variables in Astro on Vercel

  • In Astro, environment variables should be accessed using import.meta.env (e.g., import.meta.env.MY_TOKEN), not process.env, except in certain SSR scenarios. When deploying to Vercel, ensure your environment variables are set in the Vercel dashboard and accessed correctly in your code. If you are using SSR, the way environment variables are accessed can depend on the adapter, but for Vercel, import.meta.env is the standard approach for both static and SSR builds. Double-check that your tokens are referenced this way in your code and not being inlined at build time in a way that would make them unavailable at runtime Getting environment variables.

2. SSR and Adapters

  • If you are using server-side rendering (SSR) or on-demand rendering, you must have the correct adapter installed and configured. For Vercel, this means using the @astrojs/vercel adapter. If your project is trying to use SSR features without the adapter, or if the adapter is misconfigured, you may see internal server errors or blank pages On-demand rendering, Deploy your Astro Site to Vercel.

3. Error Handling and Debugging

#
  • Internal server errors (500) may not always show detailed logs in Vercel, especially if the error occurs before logging or in a part of the code that swallows errors. Astro middleware and error pages may not always run as expected depending on the adapter and the error source Error pages.
  • To debug, try creating a minimal reproduction of the issue, stripping out unrelated code, and see if the problem persists. This can help isolate whether the issue is with your environment variables, GraphQL queries, or something else Creating minimal reproductions.

4. GraphQL and API Tokens

  • If your tokens are available and valid in the Vercel environment, but your API calls fail only in production, ensure that:
    • The environment variable names are correct and match between your code and Vercel dashboard.
    • No code is accidentally exposing or inlining secrets at build time.
    • Your fetch requests are being made server-side (where secrets are available) and not client-side (where only PUBLIC_-prefixed variables are available).

5. Static vs. Server Output

  • If your product display relies on dynamic data (e.g., fetching products from Shopify at request time), you must use SSR or on-demand rendering. If your site is built as static, the data is fetched at build time, and any runtime secrets or tokens will not be available. Make sure your adapter and output mode match your data-fetching needs On-demand rendering.

Summary of Next Steps:

#
  1. Double-check that your environment variables are set in Vercel and accessed via import.meta.env in your code.
  2. Ensure you are using the correct Vercel adapter and that your output mode (static vs. SSR) matches your data-fetching requirements.
  3. If possible, create a minimal reproduction to isolate the issue.
  4. Review your code to ensure secrets are not being inlined at build time and are only accessed server-side.

If after these steps the issue persists, consider sharing a minimal reproduction with the Astro community for more targeted help Need more?.

I'm sorry, but the knowledge sources do not provide more specific troubleshooting for Shopify Headless or GraphQL integration issues beyond these general Astro deployment and environment variable practices.
