Json to PLSQL table -> ORA-00942 - json

Question

I have a json string parameter. I would like to create a function which gives back a table with the data.
I created a type:
CREATE OR REPLACE TYPE AttachmentResponseType AS OBJECT (
savePath VARCHAR (255) ,
originalFileName VARCHAR (255) ,
fileSize number(20) );
I created a list
CREATE OR REPLACE TYPE JSON_DOC_JUKEBOX_TBL IS TABLE OF AttachmentResponseType;
And a function
CREATE OR REPLACE FUNCTION JSONSTRING_TO_JB_TYPE (p_json in varchar2) return JSON_DOC_JUKEBOX_TBL as
resTBL JSON_DOC_JUKEBOX_TBL;
JSON_VAR varchar2(3000);
begin
JSON_VAR := p_json;
with x as (SELECT t.savePath, t.originalFileName, t.fileSize FROM JSON_TABLE(
JSON_VAR,
'$'
COLUMNS(
NESTED '$.AttachmentResponseType[*]'COLUMNS (
savePath varchar2(255),
originalFileName varchar2(255),
fileSize number(20)
)
)
) as t) select AttachmentResponseType(x.savePath, x.originalFileName, x.fileSize) bulk collect INTO resTBL from x;
commit;
return resTBL;
end;
I try to test it, I have a tst table for that with the same columns
declare
test JSON_DOC_JUKEBOX_TBL;
begin
test := JSONSTRING_TO_JB_TYPE('{"AttachmentResponseType" : [{
"savePath" : "dsadsad/dsadas.xaxaxa.pfg",
"originalFileName" : "xaxaxa.pfg",
"fileSize" : "12"},
{
"savePath" : "dsadsad/1111g",
"originalFileName" : "1.pfg",
"fileSize" : "1112"}]}');
INSERT INTO tst
(savePath, originalFileName, fileSize) values
(SELECT savePath, originalFileName, fileSize
FROM test);
commit;
end;
test is highlighted as 'Undefined table'
and when I run, the exception is :ORA-00942
Am I doing something wrong? should I initialise the 'test' table somehow?

Instead of using multiple TYPEs, and a FUNCTION just to insert the records, why not just use INSERT INTO...SELECT...
See example below:
CREATE TABLE tst
(
savePath VARCHAR (255),
originalFileName VARCHAR (255),
fileSize NUMBER (20)
);
INSERT INTO tst (savepath, originalfilename, filesize)
SELECT savepath, originalfilename, filesize
FROM JSON_TABLE (
'{"AttachmentResponseType" : [{
"savePath" : "dsadsad/dsadas.xaxaxa.pfg",
"originalFileName" : "xaxaxa.pfg",
"fileSize" : "12"},
{
"savePath" : "dsadsad/1111g",
"originalFileName" : "1.pfg",
"fileSize" : "1112"}]}',
'$'
COLUMNS (
NESTED '$.AttachmentResponseType[*]'
COLUMNS (savePath VARCHAR2 (255),
originalFileName VARCHAR2 (255),
fileSize NUMBER (20))));
