Not compatible with newer versions of playwright

[PATAPOsha]

Everything works fine on playwright==1.27.1
But when updating playwright to 1.31.1 -- all "interception/modifying requests" methods stop working.
like

        def intercept(route: Route, request: Request):
            headers = {
                **request.headers,
                "sec-fetch-site": "same-origin",
                "sec-fetch-mode": "no-cors",
                "sec-fetch-dest": "script",
                ...
            }
            response = self.page.request.fetch(request, headers=headers)
            body = response.text()
           ...

            route.fulfill(
                response=response,
                body=body,
                headers=response.headers,
            )

        self.page.route("*/init.js", intercept)
