PSFT EX 9.2: Fluid approval page throwing error when expense report has lines older than 60 days

Hi,

We are facing an issue with Expense report approval which is affecting only few expense reports. When the approver is clicking on "View Details" link on Expense report fluid approval page then it is throwing below error. I found this document - Doc ID 2972775.1. I verified the transaction dates on the ER and there are lines on the ER which are older than 60 days. But there are some other expense reports with transaction dates older than 60 days which are not throwing this error so I am not sure if this is completely accurate. Is this a bug or is it by design? If it is by design then is there a way to prevent this error?
