Source code

await page.route('**/*', route => {
    const url = new URL(route.request().url());
    return domainsToBlock.has(url.hostname)
      ? route.abort()
      : route.continue()
//        .catch(e => {
//          console.error('Error while continuing route', url, e);
//        });
  });

Steps

Unfortunately, I don't have a great reproduction here -- we run this blocking interception all our tests. We're seeing enough failures as below though that it is pretty consistently resulting in our test suite failing.

Expected

Historically have never run into issues with this blocking, it aborts requests for domains we've blocked and otherwise just passes all other requests through without issue.

Actual

However, since updating to 1.41.1 (from 1.40.1) we're seeing rather random route.continue: Protocol error (Fetch.continueRequest): Invalid InterceptionId. being thrown for what appear to be legitimate requests that shouldn't be failing.
