Environment variables not available on Vercel

[foxted]

Summary

Recently migrated a manual monorepo to turbo repo, and when deploying, my environment variables aren't detected.

I have tried passing the env, globalEnv & globalPassThroughEnv to the main turbo.json, didn't work. Tried the same but splitting the turbo.json into each app folder, didn't work.

I can build the project successfully locally, but when deploying to Vercel, I keep getting a message (in this case from supabase-js) that my environment variable is missing.

Any tips on getting this to work? I like the idea of the strict mode, but I'm out of ideas on how to make this work.

Found the answer:

In Vercel, had to update the build command to cd ../.. && turbo run build --filter=app-1 and use passThroughEnv in my turbo.json for each apps.

would you mind pasting a copy of your turbo.json and your package.json for future searchers please?

Main turbo.json:

{
  "$schema": "https://turbo.build/schema.json",
  "tasks": {
    "build": {
      "dependsOn": ["^build"],
      "inputs": [
        "$TURBO_DEFAULT$",
        ".env.production.local",
        ".env.local",
        ".env.production",
        ".env"
      ],
      "outputs": [".next/**", "!.next/cache/**", "dist/**"]
    },
    "lint": {
      "dependsOn": ["^lint"]
    },
    "dev": {
      "persistent": true,
      "cache": false,
      "inputs": [
        "$TURBO_DEFAULT$",
        ".env.development.local",
        ".env.local",
        ".env.development",
        ".env"
      ]
    },
    "webhook:listen": {
      "dependsOn": ["^webhook:listen"],
      "persistent": true
    },
    "check-types": {
      "dependsOn": ["^check-types"]
    }
  }
}

app1/turbo.json

{
  "extends": ["//"],
  "tasks": {
    "build": {
      "passThroughEnv": ["CLERK_SECRET_KEY", "CLERK_WEBHOOK_SECRET", "SUPABASE_URL", "SUPABASE_SERVICE_ROLE_KEY"]
    }
  }
}

app2/turbo.json

{
  "extends": ["//"],
  "tasks": {
    "build": {
      "passThroughEnv": ["CONVERT_KIT_API_KEY", "CONVERT_KIT_API_SECRET"]
    }
  }
}

The build command was overwritten directly in Vercel build settings.

And where were the .envs? was there one in the root of the monorepo or one in each app and package folder?
