API Route Inside Dockerized App Repeating Results

[sr5434]

Link to the code that reproduces this issue

https://github.com/sr5434/spelling-bee

To Reproduce

1. Create a GCP service account for the cloud TTS service.
2. Create a .env in this format: ```
   GOOGLE_APPLICATION_CREDENTIALS="/app/service-account-filename.json"
   GOOGLE_CLOUD_PROJECT="project name"

3. Build the container and run it.
4. Play the audio and submit a random piece of text.
5. Play the audio again

### Current vs. Expected behavior

I am trying to have speech for different words play. The API route should be returning a random word with its audio(and this occurs when I am testing in development). However, when I containerize my app, the API route keeps returning the same result.

### Provide environment information

Additional context

The code works as expected when running npm run dev but breaks after Dockerizing.

It turns out, the app doesn't even need to be dockerized. When you run npm run build && npm run start the same issue occurs.
