Error in creating PAL Procedure

Hi,

I am trying to create a procedure in PAL using the following script and I get the following error -

Script - CALL SYSTEM.AFL_WRAPPER_GENERATOR ('PAL_ABC', 'AFLPAL', 'ABC', PAL_ABC_SIGNATURE);

Error -  Could not execute 'CALL SYSTEM.AFL_WRAPPER_GENERATOR ('PAL_ABC', 'AFLPAL', 'ABC', PAL_ABC_SIGNATURE)' in 117 ms 623 µs .           SAP DBTech JDBC: [423]: AFL error:  [423] SYSTEM.AFL_WRAPPER_GENERATOR: line 38 col 1 (at pos 1957): AFL error exception:                    AFL  error: registration finished with errors, see indexserver trace

I have used the following scripts to create the other components -

CREATE TYPE PAL_T_ABC_DATA AS TABLE (CUSTOMER VARCHAR(60), LIFESPEND DOUBLE);

CREATE TYPE PAL_T_ABC_PARAMS AS TABLE (NAME VARCHAR(60), INTARGS INTEGER, DOUBLEARGS DOUBLE, STRINGARGS VARCHAR (100));

CREATE TYPE PAL_T_ABC_RESULTS AS TABLE (ABC VARCHAR(60), CUSTOMER VARCHAR(60));

CREATE COLUMN TABLE PAL_ABC_SIGNATURE (ID INTEGER, TYPENAME VARCHAR(100), DIRECTION VARCHAR(100));

INSERT INTO PAL_ABC_SIGNATURE VALUES (1, 'PAL_T_ABC_DATA', 'in');

INSERT INTO PAL_ABC_SIGNATURE VALUES (2, 'PAL_T_ABC_PARAMS', 'in');

INSERT INTO PAL_ABC_SIGNATURE VALUES (3, 'PAL_T_ABC_RESULTS', 'out');

Whats the issue and how can it be fixed, please advise. Thanks.
