How to fix pyppeteer.errors.NetworkError: Request interception is not enabled.

Note: Also see Pyppetteer minimal network request interception example

Problem:

You are trying to intercept a request in Pyppeteer using

page.on('request', my_intercept_request)

but you’re getting an error message like this:

Traceback (most recent call last):
  File "/usr/lib/python3.6/asyncio/events.py", line 145, in _run
    self._callback(*self._args)
  File "/usr/local/lib/python3.6/dist-packages/pyee/_compat.py", line 62, in _callback
    self.emit('error', exc)
  File "/usr/local/lib/python3.6/dist-packages/pyee/_base.py", line 106, in emit
    self._emit_handle_potential_error(event, args[0] if args else None)
  File "/usr/local/lib/python3.6/dist-packages/pyee/_base.py", line 83, in _emit_handle_potential_error
    raise error
  File "run.py", line 6, in intercept
    await request.continue_()
  File "/usr/local/lib/python3.6/dist-packages/pyppeteer/network_manager.py", line 481, in continue_
    raise NetworkError('Request interception is not enabled.')
pyppeteer.errors.NetworkError: Request interception is not enabled.

Solution

Add

await page.setRequestInterception(True)

directly after your call to

page = await browser.newPage()

This will enable request interception and your code will run just fine.
