Terraform lambda source_code_hash update with same code

Question

I have an AWS Lambda deployed successfully with Terraform:

resource \"aws_lambda_function\" \"lambda\" {
  filename                       = \"dist/subscriber         


        

Answer 1

This works for me and also doesn't trigger an update on the Lambda function when the code hasn't changed

data "archive_file" "lambda_zip" {                                                                                                                                                                                   
  type        = "zip"                                                                                                                                                                                                
  source_dir  = "../dist/go"                                                                                                                                                                                         
  output_path = "../dist/lambda_package.zip"
