Can you paste your block of code relating to subnets and VPCs here so I can try to reproduce the error?

@Manickz @l-gatillon @kk-rishang Can you do a git pull on main branch and try again with the latest code?

Hi all! I cloned the last version from main branch and it still raise the "unhandled error" exception for 'cidr_block' fields.

My script defines an aws_vpc_endpoint resource used for the db Secret rotation. In tfwrapper.py file (row 247) terravision tries to parse the aws_vpc_endpoint resource searching for the cidr_block values, but it doesn't find them.
This raises exception.

@kk-rishang @rraffaello It seems the program was detecting VPC endpoints as VPCs, I added a fix and tested it works. Please git pull the latest code and try again.

Hi @kk-rishang @rraffaello @kk-rishang @l-gatillon @Manickz Can I close this issue? The code base is now quite different from when you last used terravision. It would be great if you could have a quick look now at the latest version and tell me if there are any more issues.
