Dotnet Lambda taking too much time to deploy in AWS

Terraform HCP Terraform
1

We are trying to deploy dotnet lambda function on AWS using terraform , But we have observed 2 thing

  1. Terraform takes almost 10 min to complete the deployment of a AWS lambda function . This is only happening in Dotnet code , we have tested python one and it is working perfectly fine . Can you please let us know any insights here.
  2. We are also getting this error message on console “The code editor does not support the .NET Core 3.1 (C#/PowerShell) runtime.”. I have checked AWS documentation , it seems dotnet 3.1 is supported but not sure why we are getting this behavior

Terraform Version

0.12.13

AWS provider

provider "aws" {
  version = "=3.38.0"
  region = var.region

  assume_role {
    role_arn = var.role_arn
  }
}

Debug Output

module.lambda.null_resource.build (local-exec): -rw-r--r--. 1 centos centos 2.1M Aug 13 13:41 gdm-lpa-backend-sandbox-master-_d4uh8ycj5u.zip
module.lambda.null_resource.build: Creation complete after 7s [id=4714780671659555037]

module.lambda.aws_lambda_function.lambda: Modifications complete after 6s [id=gdm-lpa-backend-sandbox]

Apply complete! Resources: 2 added, 1 changed, 2 destroyed.

so this terraform takes almost 10 min to complete , we want to know the reason here. As i can see the lambda get deployed in 6sec only but it waits for 10 min to get the terraform complete.

Crash Output

Expected Behavior

Terraform should deploy the lambda function in 6 sec

Actual Behavior

Terraform takes almost 10 min to deploy the code to lambda function

Steps to Reproduce

  1. terraform init
  2. terraform apply
