Terraform Version

$ terraform -v
Terraform v0.12.20
+ provider.aws v2.58.0

Affected Resource(s)

• aws_lambda_alias

Terraform Configuration Files

resource "aws_lambda_alias" "alias" {
  function_name = "lambda"
  function_version = "..."
  name = "alias"
}

Expected Behavior

terraform import aws_lambda_alias.alias lambda/alias should set the attribute function_name to lambda.

Actual Behavior

terraform import aws_lambda_alias.alias lambda/alias sets the attribute function_name to the function's ARN.

Terraform will perform the following actions:

  # aws_lambda_alias.alias must be replaced
-/+ resource "aws_lambda_alias" "alias" {
      ~ arn              = "arn:aws:lambda:<region>:<account>:function:lambda:alias" -> (known after apply)
        description      = "..."
      ~ function_name    = "arn:aws:lambda:<region>:<account>:function:lambda" -> "lambda" # forces replacement
        function_version = "..."
      ~ id               = "arn:aws:lambda:<region>:<account>:function:lambda:alias" -> (known after apply)
      ~ invoke_arn       = "..." -> (known after apply)
        name             = "alias"
    }

Plan: 1 to add, 0 to change, 1 to destroy.

Steps to Reproduce

1. Create the lambda alias
2. Run terraform import
3. Run terraform plan
