With pyppeteer how to make a request with client cert? - python-3.x

Question

I have the need to reach a page using client certificate with pyppeteer,
i have seen that its possible with puppeteer itself here,
but my attempts lead to an invalid state errror with python3. Im not sure whether my attempt is entirely correct, but it follows the spirit of the issue comment in puppeteer. I would expect it to be possible, hence my attempts, here is the error:
[E:pyppeteer.connection] connection unexpectedly closed
Task exception was never retrieved
future: <Task finished coro=<Connection._async_send() done, defined at /home/data/experim/jaenv/lib/python3.6/site-packages/pyppeteer/connection.py:69> exception=InvalidStateError('invalid state',)>

During handling of the above exception, another exception occurred:

This is the attempt that leads to the above error:

await page.setRequestInterception(True)
