Loadrunner Replay Error - Hyperion EPM 11.1.2.4 login

Hi,

I have recorded a login to Hyperion Workspace 11.1.2.4 and on replay I am getting the following error after correlating sso_token:

Action.c(254): Error -26627: HTTP Status-Code=404 (Not Found) 

  [MsgId: MERR-26627]
Action.c(254): Warning -26200: At least one of the resources specified by EXTRARES has not been downloaded due to the above error(s)   [MsgId: MWAR-26200]
Action.c(254): web_submit_data("Adf.jsp_3") highest severity level was "ERROR", 768 body bytes, 268 header bytes   [MsgId: MMSG-26388]

The correlation created the following function call

    web_reg_save_param_regexp(
        "ParamName=RP_SSO_TOKEN",
        "RegExp=!\\[CDATA\\[(.*?)]]",
        SEARCH_FILTERS,
        "Scope=Body",
        "IgnoreRedirections=No",
        LAST);

The replay output does show that the parameter is being substituted.

Previous scripts that were recorded against 11.1.2.2 called web_reg_save_param which I understand is now deprecated. I also tried this same code snippet and it fails with the same error.

Code from 11.2.2.2 scripts:

 web_reg_save_param("RP_TOKEN_NO_ENCODING","LB=CDATA[","RB=]]></token>", LAST);

Any advise is appreciated.
