Invalid input syntax PLPGSQL script

Question

I have a trigger function that is going to audit transactions made on a table.

CREATE or REPLACE FUNCTION audit()
  returns trigger
  language plpgsql
as $$
begin
EXECUTE FORMAT ('INSERT INTO %I.audit VALUES (%L,%L,%L)',TG_TABLE_SCHEMA, TG_TABLE_NAME, TG_OP, now());
 RETURN NEW;
end;
$$

However I keep getting "ERROR: invalid input syntax for integer: "triggerTable" Where: PL/pgSQL function audit() line 3 at EXECUTE statement" (Where trigger table is the table that has triggered this function)

Is the I assume the syntax of my execute query is wrong, but I can't isolate where. Any feedback would be welcome

The problem is in casting to target table. Some target column is integer, but you push text there. It is same error like this:

postgres=# create table foo(a int);
CREATE TABLE

postgres=# insert into foo values('AHOJ');
ERROR:  invalid input syntax for integer: "AHOJ"
LINE 1: insert into foo values('AHOJ');
                               ^

It is looking like first column of audit table is integer (probably id), but you push table name there.

Thanks, I have an autoincrement ID field and I haven't included.

You are passing four values for three placeholders. I presume that "audit" should be a placeholder for TG_TABLE_NAME?

Silly mistake on my behalf. Updated the insert to have three values; however I get this error. ERROR: invalid input syntax for integer: "covenant" Where: PL/pgSQL function audit() line 3 at EXECUTE statement
