baseUrl not working since 0.16.0

[wong2]

Description of the bug:

I'm upgrading the sdk from 0.15.0 and found that the baseUrl requestion option stops working.

Actual vs expected behavior:

I have the following code:

const model = sdk.getGenerativeModel(
  { model: '...', safetySettings },
  { apiVersion: 'v1beta', baseUrl: this.baseUrl },
)

const chatSession = model.startChat({ safetySettings })
const stream = await chatSession.sendMessageStream(prompt)

However, the provided baseUrl didn't take effect, and the request was still sent to the default Google URL.

Any other information you'd like to share?
