Error while converting document to html

Question

"ORA-06502: PL/SQL: numeric or value error: invalid LOB locator specified: ORA-22275"
I use the procedure to convert the documents if it is not already converted before using procedure as follows
PROCEDURE "STARDOC"."HTMLOUTPUT" (
"DOCID" IN NUMBER) IS
mklob clob;
doccount number;
errorcode number;
errormessage varchar2(200);
BEGIN -- executable part starts here
SELECT COUNT(document_id) INTO doccount FROM docviewhtml where document_id=docid;
--dbms_output.put_line(doccount);
if doccount=0 then
     dbms_output.put_line('Document Not Found: Converting '||docid);
     --If document is not found run document coversion routine
     ctx_doc.filter('idxdocuments',docid, mklob,FALSE);
     INSERT INTO docviewhtml(document_id, html) VALUES (docid, mklob);
     COMMIT;
elsif doccount=1 then
     --return;
     dbms_output.put_line('Document Found');
     --if document id found then return the document content
     null;
else
     --dbms_output.put_line('Error occured');
     --need to deal with duplicate documents
     null;
end if;
dbms_lob.freetemporary(mklob);
EXCEPTION
--rollback when an exception occurs
     WHEN OTHERS THEN
          errorcode:=SQLCODE;
          errormessage:=SQLERRM;     
          dbms_output.put_line(sqlcode || ':' ||sqlerrm);
          ROLLBACK;
          LOGERROR(errorcode,errormessage);
END "HTMLOUTPUT";

You free your temporary lob, but never create it.
