How to upload images to VK Market via PHP SDK?

Question

PHP

I'm trying to upload images via the VK API PHP SDK. To get access token I use Authorization Code Flow. I am requesting with permissions VK\OAuth\Scopes\VKOAuthUserScope::MARKET, VK\OAuth\Scopes\VKOAuthUserScope::PHOTOS.
The token can be received, everything is fine.
It is also possible to get the upload_url for uploading images via the $vk->photos()->getMarketUploadServer() method.

But when I move on, strange errors appear.
The $vk->getRequest()->upload( $uploadServer['upload_url'], $img_title, $img_path ) method returns a PHP error:
Uncaught TypeError: Argument 1 passed to VK\Client\VKApiError::__construct() must be of the type array, string given, called in /vendor/vkcom/vk-php-sdk/src/VK/Client/VKApiError.php: 27. Some internal error in the SDK, with which it is not clear what to do.

I also tried using CURL directly. Returns an error: {"error":"ERR_UPLOAD_BAD_IMAGE_SIZE: market photo min size 400x400","bwact":"do_add","server":535136,"_sig":"e4c41105c5b06d61aa2f3d7cc2cf26f2"}
Although the image size is larger than 400x400.
Has anyone experienced this? What to do? Help
