APEX_JSON.get_count not recognizing JSON path - arrays

Question

We are on Oracle 11g, no chance of upgrade at this time.
This JSON comes from an outside source, no chance of reformat.
Is this JSON the problem? I am able to run htis code using simple JSON.
APEX_JSON.get_count only seems to recognize the path hits.hits
I need to create an inner loop to parse full_na
declare
l_cnt PLS_INTEGER ;
l_cnt_2 PLS_INTEGER ;
json varchar2 (32767)
