Uncaught TypeError: array_merge(): Argument #2 must be of type array, null given in [...]includes/Handler/class-wp.php line 78

[lordmatt]

I'm seeing an error being thrown for a specific mention to my site.

The line it is objecting to is:

$result = array_merge( $page, $this->parse_author_json( $response ) );

I think the cause is that parse_author_json returns null if the key does not exist but line 78 does not try to handle the null case.

		if ( ! array_key_exists( '_embedded', $json ) ) {
			return null;
		}

The ping should come from https://islandinthenet.com/sn/135307/ to https://lordmatt.co.uk/replying-to-things/okay-make-what-you-need-might-be-good-for-the-indiewebs-future-after-all/#comment-14975

It does not seem to be a problem for other links.

That's as far as I have been able to trace the problem.
