content: Error in invocation of contentFilterPrivate.isURLBlocked (Opera GX only)

It is caused by a fault in the Opera GX tracking blocker. You can fix this by disabling the tracking blocker until Opera releases a fix.

I’ve reported this bug to the developers at Opera Software a couple of days ago already:

https://opera.atlassian.net/servicedesk/customer/portals

Unfortunately, I cannot link to the issue, since their bugtracker is not public.

I solved it by disabling “Block ads” and “Block Trackers” under Settings>Privacy Protection

FIX (opera gx):

Turn off adblocker and tracking blocker. Works fine now.

Disable privacy protection on localhost page, it’s works normally.

I thought this was an issue on my website but yea seems that it’s opera

Issue is now fixed with Opera 89.0.4447.38.

Definitely a problem with Opera. Also a fault in Opera for desktop’s tracking blocker.

I came here after encountering this issue in a create react app dev server after importing a react-query custom data fetch hook when I had not yet declared state from the hook. ie:

Error encountered when useForecasts imported into App…

function useForecasts({ lat, long }) {
const fetchForecasts = async () => {
    ...
    try ...fetch(someData
    ...return data
  };
const { isLoading, error, data, isFetching } = useQuery(
    "forecasts",
    fetchForecasts
  );
return {
    forecasts: data ?? [],
    isForecastLoading: isLoading,
    error,
    isFetching,
  };
}

Error not encountered when below code is also included in App

  const { forecasts, isForecastLoading } = useForecasts(
   geoLocation.coordinates
  );

i have the same problem and i am using Opera 88.0.4412.53
