[REQUIRED] Test case

Original Stack Overflow question: https://stackoverflow.com/a/78496117/12806961

[REQUIRED] Steps to reproduce

1. Create a new Firebase Genkit project (firebase init genkit)
2. export GOOGLE_GENAI_API_KEY={key}
3. Add these lines at the top of the file:

import { defineSecret } from "firebase-functions/params";
defineSecret("GOOGLE_GENAI_API_KEY");

4. Run firebase deploy --only functions
5. Navigate to GCP > Cloud Functions > Functions > Select Function > Variables Tab

The GOOGLE_GENAI_API_KEY variable is a list, not a string.

[REQUIRED] Expected behavior

DefineSecret should create a single string environment variable and not a list with a single string value.

[REQUIRED] Actual behavior

Were you able to successfully deploy your functions?

Yes but it didn't work. I needed to change defineSecret to defineString.
