cannot convert from Object&Serializable&Comparable<?> to Date

[Anonymous]

Hi,
I am converting two strings into date data types but keeping into an error I do not fully comprehend.
This is my snippet in tMap output into the database:

(row1.Week == null || row1.Week == ("")) ? "" : TalendDate.parseDate("MM/dd/yyyy",row1.Week) 

Type mismatch: cannot convert from Object&Serializable&Comparable<?> to Date

Thanks in advance,
CM

My bad. In the output component, I had not checked the Nullable checkbox.
Talend should be more precise on which component the error exists.
Thank you @shong for your time.
