ZOHO Flow | Add Time Ticket Entry

ZOHO Flow | Add Time Ticket Entry

I'm trying to build a flow which runs whenever a form is filled in. The flow makes a ticket and adds time to that ticket.
But whenever I'm trying to use the "Add time ticket entry" I get this error message from the execution time field:

Zoho Desk says "The data is invalid due to validation restrictions

/executedTime-invalid The value passed for field '/executedTime' does not match the allowed values."


Anyone an idea how to fix this?
