What?

Module execution failing when running on terraform 0.15
There’s two issues

1. First one is not being able to use the aws provider v3

│ Error: Failed to query available provider packages
│
│ Could not retrieve the list of available versions for provider hashicorp/aws: locked provider registry.terraform.io/hashicorp/aws 3.31.0 does not match configured version constraint ~> 2.70; must use
│ terraform init -upgrade to allow selection of new versions
╵

2. When running terraform plan getting an tf 0.12 code incompatibility issue

Why?

• Being able to use the module with terraform 0.15
