Since ~March 28, 2026, user-defined environment variables are intermittently absent from process.env at runtime in a standard request/response function using the Functions v2 export default style. System variables and Netlify’s built-in URL var remain present. Netlify.env.get() also returns undefined for the affected vars. **Setup:** Single request/response function (not scheduled or background), deployed with esbuild bundler. Env vars configured with All scopes in the Netlify dashboard. No code or config changes preceded the issue. **What we’ve confirmed:** - When it occurs, Object.keys(process.env).length shows 37 keys — all system vars, zero user-defined - We implemented retry logic with exponential backoff (50–400ms, ~750ms total wait). The vars never appeared during retries — they are completely absent for the entire invocation, not delayed - The issue is intermittent: some cold starts receive env vars normally, others do not - –skip-functions-cache deploys do not resolve it - Netlify.env.get() returns undefined for the same vars **Impact:** Any handler that reads a user-defined env var (database connection, API keys, auth secrets) returns a 500. Login, checkout, and all authenticated routes fail intermittently with no code change on our side. ---

Having the same issue. No code or config changes however getting a bunch of missing environment variables on both live and branch deploys ---

Thanks for confirming, as I thought I was going mad. I see no status issue or report anywhere for this over the last 24 hours. I just had multiple users tell me. ---

Opened this ticket [Functions v2: user-defined env vars completely absent from `process.env` AND `Netlify.env.get()` - Support - Netlify Support Forums](https://answers.netlify.com/t/functions-v2-user-defined-env-vars-completely-absent-from-process-env-and-netlify-env-get/163080) Seems to be a regression of the fix on this thread?
