$post_array is of type array<string,?,{"release...elease_post_link":"?"}>, but the function expects a string|null.

It seems like the type of the argument is not accepted by the function/method which you are calling.

In some cases, in particular if PHP’s automatic type-juggling kicks in this might be fine. In other cases, however this might be a bug.

We suggest to add an explicit type cast like in the following example:

function acceptsInteger($int) { }

$x = '123'; // string "123"

// Instead of
acceptsInteger($x);

// we recommend to use
acceptsInteger((integer) $x);

6489

6490
	 * Pros:
6491
	 * - Uses only ONE css asset connection instead of 15
6492
	 * - Saves a minimum of 56k
6493
	 * - Reduces server load
6494
	 * - Reduces time to first painted byte
6495
	 *
6496
	 * Cons:
6497
	 * - Loads css for ALL modules. However all selectors are prefixed so it
6498
	 *      should not cause any issues with themes.
6499
	 * - Plugins/themes dequeuing styles no longer do anything. See
6500
	 *      jetpack_implode_frontend_css filter for a workaround
6501
	 *
6502
	 * For some situations developers may wish to disable css imploding and
6503
	 * instead operate in legacy mode where each file loads seperately and
6504
	 * can be edited individually or dequeued. This can be accomplished with
