The idea of on_error is to tolerate errors, I think.
if a column has a not null constraint, let it cannot be used with
(on_error 'null')

Based on this, I've made a patch.
based on COPY Synopsis: ON_ERROR 'error_action'
on_error 'null', the  keyword NULL should be single quoted.

demo:
COPY check_ign_err FROM STDIN WITH (on_error 'null');
1 {1} a
2 {2} 1
3 {3} 2
4 {4} b
a {5} c
\.

\pset null NULL

SELECT * FROM check_ign_err;
  n   |  m  |  k
------+-----+------
    1 | {1} | NULL
    2 | {2} |    1
    3 | {3} |    2
    4 | {4} | NULL
 NULL | {5} | NULL
