insert data with invalid input syntax for integer:"42P01"

I am still getting ERROR: invalid input syntax for integer:"42P01" when I am insert a data into the table.

CONTEXT: PL/pgSQL function cidr_staging.trigger_fct_tr_stg_adjudicative_status_ins() line 29 at assignment.

Insert query:

insert into cidr_staging.stg_adjudicative_status (receipt_number, adjudicative_action_date, adjudicative_time_stamp, adjudicative_status, mig_filename, mig_insert_dt, mig_modified_dt, mig_seq) values (E'LIN1890030316', E'20180409',E'0752',E'Dennied',E'c3_20180626_adjudicativestatus_000.txt',NULL,NULL,172011);

the trigger is:

Create or replace function cidr_staging.trigger_fct_tr_stg_adjudicative_status_in() RETURNS trigger AS $BODY$

declare

v_seq bigint:=0;

v_ErrorCode bigint;

V_ErrorMsg varchar(512)'

v_Module varchar(32):= 'TR_STG_ADJUDICATIVE_STATUS_INS';

BEGIN

BEGIN

select nextval('sq_staging') into STRICT v_seq;

if NEW.mig_seg is null then

   NEW.mig_seq:=v_seq;

enf if;

if NEW.mig_filename is null then

   NEW.mig_filename :='Unknown';

end if;

exception

when others then

   v_ErrorCode := SQLSTATE'

   v_ErrorMsg := SQLERRM;

   insert into cidrmgmt.errorlog(stamp, os_user, host, module, errorcode, erromsg) values (CURRENT_TIMESTAMP, sys_context('userenv','session_user'), sys_context('userenv','host'),v_Module, v_ErrorCode, v_ErrorMsg);

END;

RETURN NEW;

end

$BODY$

LANGUAGE 'plpgsql';

CREATE TRIGGER tr_stg_adjudicative_status_ins BEFORE INSERT ON cidr_staging.stg_adjudicative_status FOR EACH ROW

  EXECUTE PROCEDURE cidr_staging.trigger_fct_tr_stg_adjudicative_status_ins();

 

the table definition is:

create table cidr_staging.stg_adjudicative_status (

receipt_number character varying (13) not null,

adjudicative_action_date character varying(8), 

adjudicative_time_stamp character varying(4),

adjudicative_status character varying(50,

mig_file_name character varying(80) not null,

mig_insert_dt timestamp without time zone,

mig_modified_dt timestamp without time zone,

mig_seg bigint not null);

Triggers:"tr_stg_adjudicative_status_ins" before INSERT ON cidr_staging.stg_adjudicative_status FOR EACH ROW EXECUTIVE PROCEDURE cidr_staging.trigger_fct_tr_stg_adjudicative_status_ins()

even I take the "E" values out the error is still occurred but if I dropped the function and trigger, the insert is fine

thank you so much for looking into this error.
