I will be releasing a significant update that uses the Terraform binary - please test again with that once released.

@patrickchugh commented on GitHub (Nov 21, 2023):

@ViktorUJ Hello, thank you for your feedback and thanks for testing out Terravision and helping to make this a better product. I have recently completed a major revamp to the code which uses the terraform binary to download source files and generate initial relationships, before augmenting it with source code parsing as before. This is a significant departure from the previous approach and whilst slower, ensures a more accurate output and will handle all terraform in built functions now when encountered in the source. Please do a git pull and re-test again with the latest source code. If your problem is resolved, please close the the thread in github issues and mark it as completed. If not, please give as much detail as you can about the errors and include any source files if possible so I can reproduce your issue. Once again, thanks for helping and look forward to hearing from you soon.

P.

What version of Python are you using? I got that error when I attempted with Python 3.8.10. After upgrading to 3.9, I was able to move past that. I mean, I ran into a different error afterward, but it's progress.

The application progresses through most of my plan, and then when it hits a stage labeled "Checking for additional links between X resources..", it steps through a number of aws_ resources and ends with:

"Unhandled error: <class 'KeyError'>, 'count', <traceback object at 0x7f696363e580>"

Note: I initially received a similar KeyError with regard to EFS volumes, so I commented out the EFS section in terravision/modules/cloud_config.py. Just to see if it was just hanging up on that one resource.

This, BTW is on Ubuntu 20 via WSL, with Python 3.9.

Other note: I am not very proficient at this at all. I just happened across the same issue that you did, but managed to get past it.

@patrickchugh can we have a look at that one instead? this one was resolved using python 3.10.13 on ubuntu 20.04 LTS
