<?php
    public function run()
    {
        $module = $this->controller->module;
        $request = Yii::$app->request;

It seems like Yii::app->request can also be of type yii\web\Request. However, the property $request is declared as type yii\console\Request. Maybe add an additional type check?

        $identity = $module->getUserIdentity();

Are you sure the assignment to $identity is correct as $module->getUserIdentity() targeting rhertogh\Yii2Oauth2Server\Oauth2Module::getUserIdentity() seems to always return null.

        $logoutVerificationRequired = false;

        if (!$module->enableOpenIdConnect) {
            throw new ForbiddenHttpException('OpenID Connect is disabled.');
        }

        if ($identity && !($identity instanceof Oauth2OidcUserInterface)) {

$identity is of type null, thus it always evaluated to false.

            throw new InvalidConfigException('In order to support OpenID Connect '
                . get_class($identity) . ' must implement ' . Oauth2OidcUserInterface::class);
        }

        $clientIdentifier = $this->getRequestParam($request, 'client_id');

It seems like $request can also be of type yii\console\Request; however, parameter $request of rhertogh\Yii2Oauth2Server\controllers\web\base\Oauth2BaseWebAction::getRequestParam() does only seem to accept yii\web\Request, maybe add an additional type check?

        $idTokenHint = $this->getRequestParam($request, 'id_token_hint');
        $state = $this->getRequestParam($request, 'state');
        $postLogoutRedirectUri = $this->getRequestParam($request, 'post_logout_redirect_uri');

        // The `id_token_hint` is the OIDC id token (https://openid.net/specs/openid-connect-core-1_0.html#IDToken)

Inline comments must end in full-stops, exclamation marks, or question marks

        if ($idTokenHint) {

            $parser = new Parser(new JoseEncoder());

            $idToken = $parser->parse($idTokenHint);

It seems like $idTokenHint can also be of type array; however, parameter $jwt of Lcobucci\JWT\Token\Parser::parse() does only seem to accept string, maybe add an additional type check?

            $validator = new Validator();

            if (!$validator->validate($idToken, new SignedWith(

                if (!$validator->validate($idToken, new PermittedFor($clientIdentifier))) {

It seems like $clientIdentifier can also be of type array; however, parameter $audience of Lcobucci\JWT\Validation\Constraint\PermittedFor::__construct() does only seem to accept string, maybe add an additional type check?

                    throw new UnauthorizedHttpException('Invalid "aud" claim in `id_token_hint`.');
                }

                $audiences = $idToken->claims()->get('aud');
                if (count($audiences) === 1) {

It seems like $audiences can also be of type null; however, parameter $value of count() does only seem to accept Countable|array, maybe add an additional type check?

                    $clientIdentifier = $audiences[0];

The variable $client does not seem to be defined for all execution paths leading up to this point.
