Procedure Erroring: ORA-01858

Question

Hello: Here is the call stack from SQL Plus (9i):
ORA-06512: at "SYS.CALLHIST_CSV", line 147
ORA-01858: a non-numeric character was found where a numeric was expected
ORA-06512: at line 1
I have another procedure similar that runs well. I tried isolating the issue by running the sql solo and the query returns fine but when run in this procedure it errors. Originally I didn't have all the NVL and CAST. I did that to try to compensate for the error plus I need the output file to be in unicode.Thanks!
These are the field types that I thought to look out for (the others are varchars):
NUMBER DATE
CUSTOMER_ID SHIP_DATE
SEQNO STAUS_DATE_TIME
INSTALLER_ID CREATION_DATE
ESCALATION_ID COMPLETION_DATE
PROBLEM_ID
SUBJECT_ID
STATUS_ID
REASON_ID
RESOLUTION_ID
CLASS_ID
