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

                $this->cache->tag($tag)->set($key, [$response->getContent(), $header], $expire);

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

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