I have a working app with data filtered out by the security filters. When logged in to the app with custom log in page to filter data. It works completely fine. There is one scenario at the log in which posts the error " Unable to fetch app definition.

Error:Error in date time arithmetic expression. The input date time values in the expression are invalid, or the result date time value is invalid/n "

I need help in debugging this error. Any possible explanations is appreciated.

thanks in advance.
