String or binary data would be truncated (stored procedure)

I get this error when run my stored procedure.This procedure works properly for some inputs. I set day in below code : 2016/08/24 00:00:00 In this case get error but if i change to 2016/08/25 00:00:00 works currently.In my stored procedure i call Table Base Function and get data from it .I Increase length of inputs in procedure and function but don't work .The type of variable that print number of it in Error is DateCall nvarchar(128) this is same in function and stored procedure.If code is right ? should works for any inputs.

EXEC @return_value = [dbo].[ProcGetReportTRAINPDF] @StartDate = N'2016/08/24 00:00:00', @endDate = N'2016/08/31 23:59:59', @top = 50 

Msg 8152, Level 16, State 13, Procedure ProcGetReportTRAINPDF, Line 92 String or binary data would be truncated. The statement has been terminated.
