PHP Warning: preg_match() expects parameter 2 to be string, array given in wp-includes/class-simplepie.php on line 2620

Question

The server keeps returning these errors:

[Mon Jan 25 13:38:14.133045 2021] [php7:warn] [pid 18879] [client 13.66.139.39:26051] PHP Warning: preg_match() expects parameter 2 to be string, array given in /wp-includes/class-simplepie.php on line 2620

if (isset($this->data['headers']['link']) && preg_match('/<([^>]+)>; rel='.preg_quote($rel).'/', $this->data['headers']['link'], $match))
        {   
            return array($match[1]);
        }
        else if (isset($this->data['links'][$rel]))
        {
            return $this->data['links'][$rel];
        }
        return null;
    }

Can someone please explain how to fix this? The $this->data['headers']['link'] is causing the error since it's not a string and giving the preg_match an array instead.
