Description
See the attached technique export.
The generated technique looks like this:
bundle agent testing_bug(bob) {

"report_param" string => join("_", args);
"full_class_prefix" string => canonify("testing_bug_${report_param}");
"class_prefix" string => string_head("${full_class_prefix}", "1000");

Inside the call_3ede173b_6030_4340_955d_3a11c367e08d bundle the ${bob} variable is not defined and so, the _classes_noop fails to define any condition.
The generated technique should look like this instead:
bundle agent testing_bug(bob) {
vars:
"args" slist => {"${bob}"};
"report_param" string => join("_", args);
"full_class_prefix" string => canonify("testing_bug_${report_param}");
"class_prefix" string => string_head("${full_class_prefix}", "1000");
