    {
        $this->resource = tmpfile();

It seems like tmpfile() can also be of type false. However, the property $resource is declared as type resource. Maybe add an additional type check?

        $this->data();

        return $this->resource;

The expression return $this->resource could also return false which is incompatible with the documented return type resource. Did you maybe forget to handle an error condition?
