InvalidArgumentException with wp_remote_post function

[Hazem Elijla]

The folllowing code generates a PHP exception:
Overloaded object of type ... is not compatible with RecursiveArrayIterator.

I can't send array contains array or any other objects like Date

wp_remote_post( 'https://api.example.com/', [
	'body'   => [
		'name'       => 'Hazem',
		'email'      => 'hazem@example.com',
		'date'       => new DateTime( 'NOW' ),
		'additional' => [
			'example' => 1,
		]
	]
] );

After checking wp core code found that this line causing this issue.
seems like "RecursiveArrayIterator" doesn't support objects or arrays.
