<?php declare(strict_types=1);

            // and URI contains a prefix

                $request = $request->withUri($uri->withPath($newPath));
                $this->uriGenerator->setUriPrefix($prefix);

It seems like $prefix can also be of type null; however, parameter $name of Yiisoft\Router\UrlGeneratorInterface::setUriPrefix() does only seem to accept string, maybe add an additional type check?

                // rewrite alias
                $this->aliases->set('@web', $prefix . '/');
            }
        }

        return $handler->handle($request);
    }
