 * Has this been solved? I’m having the same issue. Updated to version 11.9.6 and
   also did a fresh install but error is still there.
    Line 815 in file class-get-
   products.php still has !string and I assume this is no longer supported by woocommerce?
   Any solution available?

 * Can you try updating to version 11.9.7 to see if that solves the issue at hand.
