If you are using MDF business rule for Event Reason derivation.
In your business rules for Job Information Event Reason Derivation, if you do not check if the Event Reason is 'null', this will cause Event Reason's to be over-written. 
When submitting a Leave of Absence, a Job Information record is created, with the Leave of Absence Event Reason defined on the Time Type. 
The Event Reason of the record is being over-written with a Job Information Event Reason. 
This is the cause of the application error.

Review your Job Information Event Reason Derivation business rules.
Create a statement in the 'If' conditions that checks if the event reason field's value is null before setting it through the business rule. This avoids overwriting the event reason accidentally.
