The function config was not found. Maybe you did not declare it correctly or list all dependencies?

It seems like you are loosely comparing $this->getLastClosingBodyTagPosition($response->getContent()) of type integer to the boolean false. If you are specifically checking for non-zero, consider using something more explicit like > 0 or !== 0 instead.
