PyCharm : Issue with pydevd resolver : Traceback error instead of variables values. [Odoo/Openerp v8.0]

Hi,

i came accross this issue today when using PyCharm debug on an openerp v8.0 project :

OS : Ubuntu

Python version : 2.7

PyCharm version : 2019.2.6 community

Screenshots :

Error :

Inspection :

Configuration :

Code pointed by the error :

def __get__(self, record, owner):
""" return the value of field ``self`` on ``record`` """
if record is None:
return self # the field is accessed through the owner class

if not record:
# null record -> return the null value for this field
return self.null(record.env)

# only a single record may be accessed
record.ensure_one() # LINE 825 ############################### PYDEVD ERROR POINTS HERE ##########################

try:
return record._cache[self]
except KeyError:
pass

# cache miss, retrieve value
if record.id:
# normal record -> read or compute value for this field
self.determine_value(record)
else:
# draft record -> compute the value or let it be null
self.determine_draft_value(record)

# the result should be in cache now
return record._cache[self]

Other code pointed by the same error (other line):

@property
def ids(self):
""" List of actual record ids in this recordset (ignores placeholder
ids for records to create)
"""
return filter(None, list(self._ids))

# backward-compatibility with former browse records
_cr = property(lambda self: self.env.cr)
_uid = property(lambda self: self.env.uid)
_context = property(lambda self: self.env.context)

- I haven't this issue with Odoo v11.0 / python3 in an other project.

- Odoo v8.0 runs just normal, so no issue related to it.

Thank you.
