psycopg2.DataError: invalid input syntax for integer: ""

Good day to all,

I need advice on how to solve this problem. I am new to this kind of task.
I want to insert data into my PostgreSQL DB. The field that I will store
data is a textfield but I am getting an error invalid input syntax for
integer: ""

My code so far is this:

cur_p.execute("""
INSERT INTO a_recipient (created, mod, agreed, address, honor,)
VALUES (%s, %s)""", (current_timestamp,
current_timestamp, current_timestamp, '', ''))

If I remove the agreed and the last current_timestamp, it works fine as
well if I remove the honor which is a textfield and leave the 3
current_timestamp. I don't know if it is the date field with time and
timezone or the textfield which is having an issue.

I've read some related threads in SO but the ones I saw were either related
to CSV or Flask related.

Any suggestions please?

Thanks,
J
