This is on Laserfiche Cloud. I have an Accounts Payable business process that we have been using for nearly a year. It sees a few dozen submissions each day. I had not made any changes to the process in over a week, but suddenly today, nobody can submit their approvals. We get a basic error (attached) and I do not know where to look to resolve the issue.
This is not affecting other forms as far as I know (I have been able to submit some others without the error).
