Reply To: PHP warning in logs: Undefined array key “aria-describedby_text

Hello dears,
We are seeing the same warnings ,

This is because of the updated code of add-to-cart.php ,
We disabled almost all plugins , kept only theme related and WPML plugins,

I used the code below to print $args array content ,

<?php echo print_r( $args); ?>

there is no aria-describedby_text inside the array,

Array
(
[quantity] => 1
[class] => button product_type_simple add_to_cart_button ajax_add_to_cart
[attributes] => Array
(
[data-product_id] => 17798
[data-product_sku] => Test-SKU
[aria-label] => Add to cart: “Test Item”
[aria-describedby] =>
[rel] => nofollow
)
)
1

I wonder what should be the content of “aria-describedby_text” ?
