Oracle Error Message :ORA-29531: no method putsData in class Insert

I am getting when trying to insert a new record into a table where db trigger is created as below.

Database Trigger:
SQL> create or replace trigger TRIG_REMOTE
2 AFTER INSERT ON TRN_APPL_REQUESTS
3 FOR EACH ROW
4 declare
5 szApplData varchar2(5000);
6 Result varchar2(5000);
7 my_sqlerrm VARCHAR2(150);
8 PRAGMA AUTONOMOUS_TRANSACTION; -- added for commiting the transaction...
9
10 Begin
11 dbms_output.put_line('Inside Begin');
12 szApplData := '123456789012345678901234567890abcdefghijklmn10FE1
F111111221234567891234567891234567891234';
13 dbms_output.put_line('After Assigning SZApplData');
14 TESTINSERT1(szApplData);
15 dbms_output.put_line('After Select Statement :'||result);
16 commit;
17
18 exception when others then
19 my_sqlerrm := SUBSTR(SQLERRM,1,150);
20 dbms_output.put_line('Oracle Error Message :'||my_sqlerrm);
21 End;
22 /

Trigger created.
