sqlldr Error with IP Address

Hello Team,

I have a migration tool which uses sqlldr utility to load data from one oracle database (11g)  to another oracle database (12c).

The tool construct the script with the following parameters

IP:PORT:SID

USERNAME

PASSWORD

DIRECTORY

The migration tool uses the parameters above to construct the script below to migrate the data

sqlldr userid=USERNAME/psswd@xx.xx.xx.xx:1522:SID control=RSA_ALL_IND_COLUMNS_control_file_v2.ctl log=RSA_ALL_IND_COLUMNS_V2_log direct=TRUE

However, the process fails with the below error.
