I'm also having this problem. Can anyone help?

@rodrigo-segui @thiagoalexandria Can you try to do a git pull with the latest code and see if this is fixed? If not please supply some sample source so I can try to reproduce the error. Thanks!

I'm facing the same error, @patrickchugh it generates the plan, reads it, but when it reaches the Conditional resource list stage, it fails with an error indicated in the issue:

Unhandled error: <class 'TypeError'>, unsupported operand type(s) for +: 'bool' and 'str', <traceback object at 0x108641880>

Here's the link to the repository with the code I'm testing.

@thiagoalexandria I fixed it and was able to get this to run when I tagged some subnets. Please download the latest code and try again.

Enriched graphviz dictionary:

{
    "aws_instance.webserver": [
        "aws_lb.elb"
    ],
    "aws_lb.elb": [
        "aws_alb.elb"
    ],
    "aws_security_group.allow_http": [
        "aws_instance.webserver",
        "aws_lb.elb"
    ]
}

Output JSON Dictionary :
{
    "aws_instance.webserver": [
        "aws_lb.elb"
    ],
    "aws_lb.elb": [
        "aws_alb.elb"
    ],
    "aws_security_group.allow_http": [
        "aws_instance.webserver",
        "aws_lb.elb"
    ]
}

Exporting graph object into file architecture.json

Completed!
