Container is a compulsory field and needs to be filled

Hello

As part of a process step we are calling a script which inserts into ADSACCOUNT table. Below is the script. However, the process step is failing with the error below

2016-07-19 12:36:11 -05:00 - VI.JobService.JobComponents.ScriptComponent - bda451a7-63ca-4818-b3a5-63749b654067: Errors occured
    Optimizing by using the existing connection.
    [810222] Error executing script 'XXX_SA_WriteToADSACCOUNT'.
    [810008] Could not save object Active Directory user accounts ( []).
    [810077] Active Directory user accounts: Container is a compulsory field  and needs to be filled.

We are passing uid_adscontainer as an output from the previous process step. Please advise what we are missing here

Thanks in advance
