howt to access values in data container

hi,

I tried various functions but its just frustrating...

users.csv

ClassExpression,uid,name,group,ssh_key
weirdos,mscott,Michael 
Scott,pathetic,ssh-someSupERsecretKey287483438dsdjhdsdsdjahhsgdsg
weirdos,jkras,John 
Krasinski,pathetic,ssh-someSupERsecretKey287483438dsdjhdsdsdjahhsgdsg
twats,tflen,Toby 
Flenderson,tedious,ssh-someSupERsecretKey287483438dsdjhdsdsdjahhsgdsg
zombie,fired,Get 
OUT!,buzzoff,ssh-someSupERsecretKey287483438dsdjhdsdsdjahhsgdsg

test promise:

bundle agent parent_bundle
{
  classes:

      "weirdos";
      "twats";
      "zombie";

  vars:
      "data_file" string => "users.csv";
      "d" data => classfiltercsv($(data_file), "true", 0);

      "parameter_name"        slist => getindices("d");
      "parameter_name_sorted" slist => sort(parameter_name, lex);

      "cvalues"        slist => getvalues("d");
      "cvalues_sorted" slist => sort(cvalues, lex);

      "raw" data => @(d);

  methods:

   "call_remove"     usebundle => child_bundle("$(this.bundle).d"),
                     handle => "dba_user_guard",
                     classes => results("bundle", 
"itsv_DABA_USER_NOT_JUSTIFIED");


  reports:

      "All users in parent function: data: $(with)" with => 
string_mustache("{{%-top-}}", d);

      "Bonkers index is number instead of key name: Key: $(parameter_name) 
-> Value: $(cvalues)";

      "Totally useless for practical usage: $(d[0])";


}

bundle agent child_bundle (info) {

    vars:


          "user_crap1" slist => getindices("$(info)");

          "bla" data => mergedata("info");
          "user_crap2" slist => getindices("$(bla)");

          "user_crap3" slist => getvalues("info[uid]");

          "bla_$(user_crap1)" string => format("%S", "info[$(user_crap1)]");


    reports:

        "child function, only numbers instead if key names : data: $(with)" 
with => string_mustache("{{%-top-}}", user_crap1);

        "child funtion, mergedate produces empty output: $(with)" with => 
string_mustache("{{%-top-}}", user_crap2);

        "child function, getvalues also not working : data: $(with)" with 
=> string_mustache("{{%-top-}}", user_crap3);

        "Some mehtod from the docs, also nothing: $(user_crap1): 
$(bla_$(user_crap1))";

}


bundle agent __main__
{
  methods:
      "parent_bundle";
}

data format:

 {
    "group": "pathetic",
    "name": "Michael Scott",
    "ssh_key": "ssh-someSupERsecretKey287483438dsdjhdsdsdjahhsgdsg",
    "uid": "mscott"
  },
  {
    "group": "pathetic",
    "name": "John Krasinski",
    "ssh_key": "ssh-someSupERsecretKey287483438dsdjhdsdsdjahhsgdsg",
    "uid": "jkras"
  },
  {
    "group": "tedious",
    "name": "Toby Flenderson",
    "ssh_key": "ssh-someSupERsecretKey287483438dsdjhdsdsdjahhsgdsg",
    "uid": "tflen"
  },
  {
    "group": "buzzoff",
    "name": "Get OUT!",
    "ssh_key": "ssh-someSupERsecretKey287483438dsdjhdsdsdjahhsgdsg",
    "uid": "fired"
  }
