The import.meta.env.MODE always resolves to development

[pawelgrzybek]

Is there an existing issue for this?

• I have checked for existing issues https://github.com/getsentry/sentry-javascript/issues
• I have reviewed the documentation https://docs.sentry.io/
• I am using the latest SDK release https://github.com/getsentry/sentry-javascript/releases

How do you use Sentry?

Sentry Saas (sentry.io)

Which SDK are you using?

@sentry/astro

SDK Version

8.19.0

Framework Version

Astro 4.13.0

Link to Sentry event

No response

Reproduction Example/SDK Setup

import { defineConfig } from "astro/config";
import netlify from "@astrojs/netlify";

import sentry from "@sentry/astro";

// https://astro.build/config
export default defineConfig({
  output: "hybrid",
  adapter: netlify(),
  integrations: [
    sentry({
      dsn: "***",
      environment: import.meta.env.MODE, // 👈 👈 👈
      sourceMapsUploadOptions: {
        project: "website",
        authToken: process.env.SENTRY_AUTH_TOKEN,
      },
    }),
  ],
});

Steps to Reproduce

Any exception on the website logged to Sentry comes back with development env meta data.

Sentry.captureMessage("Example");

Expected Result

As per the Astro documentation, I would expect import.meta.env.MODE to resolve to "development" for astro dev and "production" for astro build.

Actual Result

Always resolves to "development".

Hello, those environment variables are coming from Astro. I just tested it in an example Astro project without Sentry and could reproduce it. As this is not Sentry-related, you could file an issue with a reproduction in the Astro repository. There is also a recent issue about this: withastro/astro#11282

Thanks for reaching out anyways. I will close this issue for now, as this cannot be fixed on our side.

Thanks a lot for your comment @s1gr1d very helpful! I am going to reopen this bug on astro repo, as the current one has been closed by automated system due to a lack of reproduction link. I made one: https://stackblitz.com/edit/github-qyxzsr

Have a fab day @s1gr1d
