change text problem woocommerce_get_availability_text

Hi, I need different text availability for one product category, I truyng:

/* backorder text on single product page */
 
function so_42345940_backorder_message( $text, $product ){
	
  if ( $product->managing_stock() && $product->is_on_backorder( 1 ) ) {
	  
	  $text = __(' This product can be ordered, the delivery time is 12-22 days. ', 'your-textdomain' );
	  
	  $idcat =  wc_get_product_term_ids( wc_get_product()->get_id(), 'product_cat' );
	  if(($idcat!="") && ($idcat[0] == 95)) 
	   {
		  $text = __(' This product can be ordered, the delivery time is 1-5 working days. ', 'your-textdomain' );
	   }
    
  }
  return $text;
}

add_filter( 'woocommerce_get_availability_text', 'so_42345940_backorder_message', 10, 2 );

When I test – all work, but after few days I see that my snippet are disabled because error – https://i.imgur.com/Utf9GWK.png
There are probably some conditions occurring that cause the error… What could it be? I think I need to make additional conditions before executing the code.

thanks
