Catching org_internal 403 error via Google's OAUTH & Socialite?

Hi all

I have google OATH setup via socialite (only for within our organisation) and everything is working fine.

One thing I'd like to try and do is catch this "error" and get redirected back to our login page with a custom message telling the user that they do not belong to our organisation.

In principle this works fine, they can just hit the back button... but for fluidity and design, I'd like to catch this and redirect back to our home page.

Is this even possible? If so, how would you recommend I go about it?

public function show()
    {
        return view('auth.login');
    }

    public function redirectToProvider($driver)
    {
        if( ! $this->isProviderAllowed($driver) ) {
            return $this->sendFailedResponse("{$driver} is not currently supported");
        }

        try {
            return Socialite::driver($driver)->redirect();
        } catch (Exception $e) {
            // You should show something simple fail message
            return $this->sendFailedResponse($e->getMessage());
        }
    }


    public function handleProviderCallback( $driver )
    {
        try {
            $user = Socialite::driver($driver)->user();
        } catch (Exception $e) {
            return $this->sendFailedResponse($e->getMessage());
        }

        // check for email in returned user
        return empty( $user->email )
            ? redirect()->intended('/login?failed=1')
            : $this->loginOrCreateAccount($user, $driver);
    }

    protected function sendSuccessResponse()
    {
        return redirect()->intended('/');
    }

    protected function sendFailedResponse($msg = null)
    {
        return redirect()->intended('/login?failedResponse='.$msg);
    }

    protected function loginOrCreateAccount($providerUser, $driver)
    {
        // check for already has account
        $user = User::where('email', $providerUser->getEmail())->first();

        // if user 
        if( $user ) {
            // update the avatar and provider that might have changed
            $user->update([
                'avatar' => $providerUser->avatar,
                'provider' => $driver,
                'provider_id' => $providerUser->id,
                'access_token' => $providerUser->token
            ]);
        } else {
            return redirect()->intended('/login?noUser=1');
        }

        // login the user
        Auth::login($user, true);

        return $this->sendSuccessResponse();
    }

    private function isProviderAllowed($driver)
    {
        return in_array($driver, $this->providers) && config()->has("services.{$driver}");
    }
