terraform_map_duplicate_keys for .tfvars files

[ericrichtert]

I's like to do some detection on duplicate keys in a map. terraform_map_duplicate_keys should do the trick, but our variables are populated in a .tfvars file.

With or without the --var-file=X.tfvars option, there is no detection of the duplicate keys. Is there a way to check the content of the .tfvars file?

Versions:
TFLint version 0.52.0

• ruleset.terraform (0.9.0)

BTW: 0.9.1 was the same behaviour

Unfortunately, variable definitions files are not currently supported in this rule.
