      why is this not

I find it very helpful to distill problems down into a small easily run
and reproducible policy and build up.

So, I took some of date from your data container to make a small mock
....

,----
| bundle agent __main__
| {
|    vars:
|       "my_data" data => '[{"package":"bash-5.0.18-1"},{"package":"bzip2-1.0.8-2"}]';
|       "my_data_values" slist => getvalues( my_data );
| 
|    reports:
|       "CFEngine $(sys.cf_version)";
| }
`----

We can see that `getvalues()' on the data container returns the list of
/key/ *values*.

| default:main.my_data                     [{"package":"bash-5.0.18-1"},{"package":"bzip2-1.0.8-2"}]    source=promise                                                                   
| default:main.my_data_values               {"bash-5.0.18-1","bzip2-1.0.8-2"}                           source=promise

You were trying to get values from the `package' key of the
`DEBUG_my_data' data container, but there is no `package' key, there is
an array of dictionaries where each dictionary has a `package' key.

,----
| "DEBUG_pkg" slist => getvalues("DEBUG_my_data[package]");
`----

You could get values from an numerical index, for example:

,----
| bundle agent __main__
| {
|    vars:
|       "my_data" data => '[{"package":"bash-5.0.18-1"},{"package":"bzip2-1.0.8-2"}]';
|       "my_data_values" slist => getvalues( "my_data[1]" );
| 
|    reports:
|       "CFEngine $(sys.cf_version)";
| }
`----

,----
| R: CFEngine 3.19.0a.da01eaa81
| Variable name                            Variable value                                               Meta tags                                Comment                                 
| default:main.my_data                     [{"package":"bash-5.0.18-1"},{"package":"bzip2-1.0.8-2"}]    source=promise                                                                   
| default:main.my_data_values               {"bzip2-1.0.8-2"}                                           source=promise
