FND_RUN_FUNCTION.get_run_function_url View Contracts (Contracts Workbench User)

Hi,

I am trying to get the url to view contract detail for any contract but I am getting the following error  below after running this code:

DECLARE

   v_out   VARCHAR2 (500);

BEGIN

   v_out :=

      FND_RUN_FUNCTION.get_run_function_url (

         p_function_id         => 1026588,

         --P_FUNCTION_NAME => 'OKC_REP_AU_CONTRACT_DETAILS',

         p_resp_appl_id        => 510,

         p_resp_id             => 51552,

         p_security_group_id   => 0,

         p_parameters          => 'contractId=' || 10852 || '&' || 'retainAM=Y' || '&' || 'addBreadCrumb=Y',

         p_override_agent      => NULL,

         p_lang_code           => NULL,

         P_ORG_ID              => 83,

         p_encryptParameters   => FALSE);

   DBMS_OUTPUT.put_line (v_out);

END;

Any help would be greatly appreciated. Thank you
