Same issue here, did you get it to work?

same with Terraform 0.13.4 OS windows WSL ubuntu 18.04 Install via pip3 Python 3.6.9 BlastRadius version (0.1.23)

I was able to "fix" this by changing the regex to be r"(\[root\]\s+)*(?P<module>[^.]+)\.(?P<type>\S+)(\.\S+)?". I still haven't got it to generate a graph but I think that's my impatience at the moment.

Anyone got this one working?

Same here... Installed with pip3 Terraform v0.14.5 Python 3.6.7 WSL with Ubuntu 18.04 BlastRadius 0.1.23

I got it to render a graph by changing the regex as well, in blastradius/handlers/dot.py to be

m = re.match(r'(\[root\]\s+)*(?P<module>\S+)\.(?P<type>\S+)[. ]\S+', label)

Not the [. ] after the capture for the <type> group. The offending label that was crashing for me was

[root] module.kv (close)

This character class handles a . or a \s after a module type

I'll submit a PR maybe by the weekend

Thanks @leriksen, also I ended up finding this one - https://github.com/kmussel/blast-radius/. It has some updates and fixes that made it work. There are more commits that may be beneficial to bring back in.

Closed. I found alternative to visual infrastructure from Terraform.
