Hi all,
I am using Contrail 3.2.5.0.
I've noticed a Python exception logged in contrail-api.log when deleting a
network or an IPAM:
The above is a description of an error in a Python program. Here is the call
trace:
Traceback (most recent call last):
File "/usr/lib/python2.7/site-packages/vnc_cfg_api_server/vnc_db.py", line
323, in _dbe_subscribe_callback
self._dbe_delete_notification(oper_info)
File "/usr/lib/python2.7/site-packages/vnc_cfg_api_server/vnc_db.py", line
425, in _dbe_delete_notification
r_class.dbe_delete_notification(obj_info, obj_dict)
File "/usr/lib/python2.7/site-packages/vnc_cfg_api_server/vnc_cfg_types.py",
line 1475, in dbe_delete_notification
cls.addr_mgmt.net_delete_notify(obj_ids, obj_dict)
File "/usr/lib/python2.7/site-packages/vnc_cfg_api_server/vnc_addr_mgmt.py",
line 785, in net_delete_notify
if obj_id in self._subnet_objs:
TypeError: unhashable type: 'dict'
In both cases, the error happens when trying to execute the following line from
vnc_cfg_api_server/vnc_addr_mgmt.py:
if obj_id in self._subnet_objs:
This line appears in the following functions:
net_delete_notify
ipam_delete_notify
I've added some logs and I have noticed that obj_id is a dictionary and it
can't be a key in the dictionary self._subnet_objs.
The exception appears because a dictionary is mutable in Python and it can't be
used as a key for another dictionary.
However, even if the exception occurs, the network/IPAM is successfully deleted.
Thanks,
Anda
