ALERT Error getting signature: 400 – App invalid

I am seeing these message in my logs.

2024-08-06T07:01:08+00:00 ALERT Error getting signature: 400 – App invalid, {“order_id”:”xxxxxxx”,”order_item_id”:”yyyyy”,”ali_id”:”123456789101112″}

Is this message something I should be worried about. This is the first time I am seeing these messages in my logs today.
