ValueError: a string literal cannot contain nul (0x00) characters

Asked by Mouna on 2017-07-13

I cannot understand the error, because already I installed the module on odoo10, ubuntu 14 and it works fine, but when I installed it on odoo10, ubuntu 16 and I tried to work with it gives me this error

    'biometric_device': self.id, }

the problem is solved by on /opt/odoo/odoo/sql_db.py commenting those lines:

#from tools import parse_version as pv
#if pv(psycopg2.__version__) < pv('2.7'):
# from psycopg2._psycopg import QuotedString
  # def adapt_string(adapted):
   # """Python implementation of psycopg/psycopg2#459 from v2.7"""
    # if '\x00' in adapted:
     # raise ValueError("A string literal cannot contain NUL (0x00) characters.")
      # return QuotedString(adapted)

    #psycopg2.extensions.register_adapter(str, adapt_string)
