Hi there,

Hi @kwinczek

It seems like it is not able to identify a node correctly. I've pushed a small change for logging the nodes and edges detected.

Can you run the application with DEBUG=true bundle exec ruby ...

If that doesn't work, would you mind sharing the generated json file with me?

aws ec2 describe-security-groups

You can send it to me at whynospam-awsviz@yahoo.co.in . I am able to run the application with the security groups configured by me and so I'm unsure why this is failing.

I found that this fixed this issue #8

@ferrants , thanks for fixing this. I'll merge the pull request shortly.

I'm assuming that the debug logging help validate this issue? I'm unsure why AWS would provide a blank name for any node. I hope that there isn't a missing scenario that the tool should support :)

I did a:

$ DEBUG=true bundle exec ruby lib/visualize_aws.rb -a $AWS_ACCESS_KEY_ID -s $AWS_SECRET_ACCESS_KEY -f viz.svg | grep node | sort -u

and in the output saw a:

node:

Not sure why it would be blank, I didn't dig in too much, just found that it worked for me.

Thanks. Merged #8
