Update a product return error : Error: Missing parameter data [woocommerce_api_missing_callback_param] 400

[RazV3R]

I have tested with these and they worked

print_r( $client->products->get() ); print_r( $client->products->get( $product_id ) ); print_r( $client->products->create( array( 'title' => 'Test Product', 'type' => 'simple', 'regular_price' => '9.99', 'description' => 'test' ) ) ); print_r( $client->products->delete( $product_id, true ) );

but when I do update product it doesn't update and show error print_r( $client->products->update( $product_id, array( 'title' => 'Yet another test product' ) ) ); :Error: Missing parameter data [woocommerce_api_missing_callback_param] 400 stdClass Object ( [headers] => Array ( [0] => Accept: application/json [1] => Content-Type: application/json [2] => User-Agent: WooCommerce API Client-PHP/2.0.1 )

I'm facing same issue when updating a product using API. Did you solve this?
