ModuleNotFoundError: No module named 'playwright' during Firebase function deployment

[chenei]

[REQUIRED] Environment info

firebase-tools: 13.29.1

Platform: macOS

[REQUIRED] Test case

A minimal example where playwright module is imported in the scraper_with_pw.py file.

from playwright.async_api import async_playwright, Browser, Page

# Example function that uses Playwright
async def fetch_page():
    async with async_playwright() as p:
        browser = await p.chromium.launch()
        page = await browser.new_page()
        await page.goto('https://example.com')
        content = await page.content()
        await browser.close()
    return content

[REQUIRED] Steps to reproduce

1. Install dependencies using pip install -r requirements.txt which includes playwright.
2. Run the Flask app locally using firebase emulators:start --only functions.
3. Deploy the Firebase function using firebase deploy --only functions.
4. The error occurs when the function is triggered: ModuleNotFoundError: No module named 'playwright'.

[REQUIRED] Expected behavior

The playwright module should be successfully imported and used in the Firebase function, and the function should execute without errors.

[REQUIRED] Actual behavior

When running locally, everything works fine. However, when deploying the Firebase function, it fails with the following error:

ModuleNotFoundError: No module named 'playwright'

Additionally, the function deployment fails with the error:
`Failed to load function definition from source: FirebaseError: Functions codebase could not be analyzed successfully. It may have a syntax or runtime

Thanks for creating a detailed report, @chenei! I’m working on reproducing this, but so far no errors are being raised when invoking the function or deployments. I created this mcve to try and replicate the setup you have. Could you let me know if I may be missing anything here?

Also, just to verify, does the ModuleNotFoundError: No module named 'playwright' occur when triggering the function or during deployment?
