[infa-niksingh]

This error message is in both python 2.7 and 3.7
I'm able to fix it by modifying file /home/ec2-user/.virtualenvs/aardvark/lib/python2.7/site-packages/swag_client-0.2.10-py2.7.egg/swag_client/util.py and changing namespace = fields.String(required=True, missing='accounts') to namespace = fields.String(required=False, missing='accounts')

Though, I'm not sure what might be breaking because of that.

I'm unable to reproduce this:

(aardvark) ➜  aardvark git:(master) aardvark config
No config

Aardvark can use SWAG to look up accounts. See https://github.com/Netflix-Skunkworks/swag-client
Do you use SWAG to track accounts? [yN]: y

[Andrew Replogle]

@infa-niksingh @mcpeak I changed setup.py to pull swag-client 0.4.6 and change Queue to queue (using python 3.7.2) and I'm able to get the api_server running.

[Travis McPeak]

Huh, I'm still struggling to reproduce this. @foglogle are you seeing the same issue as @infa-niksingh generating config?

[Andrew Replogle]

yeah, whether I use python 2.7 or 3.7 using swag-client 0.2.10 I get the same issue with missing accounts. Once I updated swag-client 0.4.6 I was able to get up and going just fine.

[Travis McPeak]

Interesting, I'll cut an upgrade and deploy to test instance. Thanks for reporting.

[Andrew Replogle]

If you want to reproduce, I'm able to do it consistently with this Dockerfile
docker build -t aardvark-test -f Dockerfile .

FROM python:2.7 


RUN cd /opt && \
    git clone https://github.com/Netflix-Skunkworks/aardvark.git && \
    cd aardvark && \
    python setup.py develop && \
