function wp_remote_retrieve_header expects array|WP_Error, httpReturnType given.

[MocioF]

Hi,
I'm using wordpress-stubs with PHPStan for a plugin.
One of my methods returns the result of wp_remote_get() so I wrote in its phpdoc's comment:
@return httpReturnType|WP_Error

Now when I use the returned value in another method calling wp_remote_retrieve_header
PHPStan says
Parameter #1 $response of function wp_remote_retrieve_header expects array|WP_Error, httpReturnType given.

Why httpReturnType is not seen as an array?

Hello @MocioF!

Thank you for your report.

There is no httpReturnType type. That variable holds an array shape.
Please write that array shape into your method.

Line 5 in 5b0b623

$httpReturnType = 'array{headers: \WpOrg\Requests\Utility\CaseInsensitiveDictionary, body: string, response: array{code: int,message: string}, cookies: array<int, \WP_HTTP_Cookie>, filename: string|null, http_response: \WP_HTTP_Requests_Response}|\WP_Error';

Thanks @szepeviktor , this is what I'm doing now.
Not sure if this can help, but now PHPStan says: Class WP_Http_Cookie referenced with incorrect case: WP_HTTP_Cookie.

Class WP_Http_Cookie referenced with incorrect case: WP_HTTP_Cookie.

That is an error.

wordpress-stubs/functionMap.php

Lines 5 to 9 in 5b0b623

	$httpReturnType = 'array{headers: \WpOrg\Requests\Utility\CaseInsensitiveDictionary, body: string, response: array{code: int,message: string}, cookies: array<int, \WP_HTTP_Cookie>, filename: string|null, http_response: \WP_HTTP_Requests_Response}|\WP_Error';
	if (file_exists(sprintf('%s/source/wordpress/wp-includes/Requests/Cookie/Jar.php', __DIR__))) {
	$httpReturnType = 'array{headers: \Requests_Utility_CaseInsensitiveDictionary, body: string, response: array{code: int,message: string}, cookies: array<int, \WP_HTTP_Cookie>, filename: string|null, http_response: \WP_HTTP_Requests_Response}|\WP_Error';
