Resolved "undefined provider" warnings by explicitly declaring the AWS provider inside the affected modules using a required_providers block, ensuring Terraform correctly maps custom provider aliases to the hashicorp/aws source and avoids fallback assumptions.

│ Warning: Reference to undefined provider
│ 
│   on vpc-peering.tf line 6, in module "peering":
│    6:     aws.requestor = aws.virginia
│ 
│ There is no explicit declaration for local provider name "aws.requestor" in module.peering, so Terraform is assuming you mean to pass a configuration for "hashicorp/aws".
│ 
│ If you also control the child module, add a required_providers entry named "aws.requestor" with the source address "hashicorp/aws".
