I want date to be entered from user which should not be a back date means it should be ahead of today’s date. If date is a back date then the same date entity should be re-prompted.
There is no provision to restrict the user conditionally while entering. Hence, we will validate the value only after the user-entered value is received to the entity.
1- Prompt the user with Entity node for date value.
2- Then, add a script node after the entity node.
3- If the date entered is previous date, then return false otherwise true.
If returned value through script is true, then you can proceed with the flow, otherwise, connect to the entity node again.
Let us know if you need any further clarification.
