ERRORS ON CHANGE OF ORDERs STATUS

Hi, I am using DOKAN MULTIVENDOR. When I login as a Vendor, go to ORDERS, select a number of orders in order to change their status en masse, I get the following FATAL ERROR message. When I check the orders again, the change the change in status has been made, despite this error. Note that the orders are mainly Completed status, changing for test reasons to Processing.

FOLLOWING THE MESSAGE I GET
