Output errors

The error message “module.aws_vpc is an object. This object does not have an attribute named ‘cidr_block’” typically occurs when you are trying to access an attribute on an object that does not have that attribute defined.

In this case, it seems that you are trying to access the cidr_block attribute on an object that is returned by the module.aws_vpc module. However, this object does not have a cidr_block attribute defined, which is causing the error.

To resolve this error, you should verify that you are using the correct object and attribute names in your Terraform code. Double-check that the module you are referencing is actually returning an aws_vpc resource, and that the cidr_block attribute is defined on that resource.

main.tf

resource "aws_vpc" "this" {
  cidr_block           = var.vpc_cidr
  instance_tenancy     = "default"
  enable_dns_hostnames = true
  enable_dns_support   = true

  lifecycle {
    create_before_destroy = true
  }

  tags = local.tags
}

outputs.tf

output "vpc_cidr" {
  description = "The CIDR block for the VPC"
  value       = aws_vpc.this.cidr_block
}

error message

module.aws_vpc is a object
This object does not have an attribute named "cidr_block".

To verify that you are using the correct object and attribute names in your Terraform code, you can use the Terraform console command to interactively evaluate expressions against your Terraform configuration and state.

Here’s an example of how you can use the Terraform console command to verify that the module.aws_vpc object contains an aws_vpc resource and that this resource has a cidr_block attribute:

Open a terminal window and navigate to the directory containing your Terraform configuration files.

Run the terraform console command to open the Terraform console.

Once the console is open, you can evaluate expressions against your Terraform configuration and state. To check if the module.aws_vpc object contains an aws_vpc resource, run the following command:

> module.aws_vpc.aws_vpc.this

This should return the aws_vpc resource object that was created by the aws_vpc module.

To verify that the aws_vpc resource object has a cidr_block attribute defined, run the following command:

> module.aws_vpc.aws_vpc.this.cidr_block

This should return the value of the cidr_block attribute for the aws_vpc resource.

By using the Terraform console, you can interactively test and verify that your Terraform code is correct and that the objects and attributes you are using are defined as expected.
