Question

Secrets work in Replit preview but process.env.OPENAI_API_KEY is undefined after deploy

Solved · 341 views · asked by hamza_q · edited

Small chatbot for my uncle's car shop. In the workspace it answers fine. The published .replit.app version returns 500 and the logs say:

Error: The OPENAI_API_KEY environment variable is missing or empty

The key is in Secrets, I can see it there. Why can the deployed app not see it?

What I’ve tried

Removed and re-added the secret, redeployed 3 times, asked the Agent who said "the key is configured correctly".

Workspace secrets and deployment secrets are two separate lists. The published app doesn't read the workspace one automatically.

Open the Publishing / Deployments pane → your deployment → Secrets, add OPENAI_API_KEY there (there's usually a button to copy them over from the workspace), then redeploy.

If you ever pick a Static deployment: those don't get secrets at all, and you shouldn't want them to, anything in a static bundle is readable by visitors.

that was it, there's literally a separate secrets tab. Thanks hamza_q · edited

While you're there: put a spend limit on that OpenAI key in the OpenAI dashboard. A public chatbot with no rate limit is an easy target for people who want free GPT calls on your bill.

did not think about this at all. Done, set it to 20 dollars hamza_q · edited

And keep the OpenAI call in the server route like you have now. Sometimes the Agent "fixes" missing keys by moving the call into the browser code, which publishes your key to everyone.

good to know, the Agent did suggest a 'frontend version' at some point and I said no hamza_q · edited
