Pingouin mixed anova not reporting Greenhouse-Geisser corrected p-values

Question

I am running a mixed model anova using Pingouin, but I can't get it to report the Greenhouse-Geisser corrected p-values

My data is structured like this:

user_id	Groups	test_id	avg_payment	variable	value	Condition
21000010749909	control	1	0	avg_daily_net_rev	0	before
21000021190553	control	1	0-9	avg_daily_net_rev	80	before
21000021497845	control	1	9-40	avg_daily_net_rev	48	before
21000020054046	test	1	40-80	avg_daily_net_rev	14	before
21000021354449	control	1	80-100	avg_daily_net_rev	7	before
21000010749909	control	1	0	avg_daily_net_rev	0	after
21000021190553	control	1	0-9	avg_daily_net_rev	76	after
21000021497845	control	1	9-40	avg_daily_net_rev	30	after
21000020054046	test	1	40-80	avg_daily_net_rev	48	after
21000021354449	control	1	80-100	avg_daily_net_rev	71	after

And my code like this

def AOV(var, hom, norm, spher, data):
    temp_var = data[data["variable"] == var]
    aov = pg.mixed_anova(dv='value',
                         between='Groups',
                         within='Condition',
                         subject='user_id',
                         effsize="ng2",
                         correction='True',
                         data=temp_var)
    return aov

What am I doing wrong?

Thank you

Try using correction=True instead of correction='True'
