pyNetBox throws exception ConnectionError when allocating an IP, even if it was successfully allocated

[Yuliya-H]

Trying to allocate IP in a few threads in parallel via :

avail_ips = DetailEndpoint(iprange, "available-ips", custom_return=IpAddresses)
address = avail_ips.create()

Getting ConnectionError which raises BadStatusLine error, even when IP is allocated:

http.client.BadStatusLine: {"id":384,"url":"http://192.168.122.209:8000/api/ipam/ip-addresses/384/","display":">[10.10.0.19/24](https://10.10.0.19/24)","family":{"value":4,"label":"IPv4"},"address":"[10.10.0.19/24](https://10.10.0.19/24)","vrf":{"id":1,"url":"http://192.168.122.209:8000/api/ipam/vrfs/1/","display":"admin","name":"admin","rd":null},"tenant":null,"status":{"value":"active","label":"Active"},"role":null,"assigned_object_type":null,"assigned_object_id":null,"assigned_object":null,"nat_inside":null,"nat_outside":[],"dns_name":"","description":"","tags":[],"custom_fields":{},"created":"2022-12-21T13:08:20.549255Z","last_updated":"2022-12-21T13:08:20.549284Z"}HTTP/1.1 201 Created

One more problem here is that the HTTP status goes after the response json.

pynetbox does not raise ConnectionErrors, it's some underlying module that's doing that.

Are you using the same pynetbox.api object (= the same requests.Session) in all those threads? I'm not a Python threading expert but I'm thinking if that could cause the responses to get messed up. See also: https://github.com/psf/requests/issues/2766

Yes , indeed I'm using one Session. I will try to separate and test this way, thanks

Everything worked OK when using separate Sessions.
