Terraform CLI and Terraform AWS Provider Version

$ terraform -v
Terraform v0.14.4
+ provider registry.terraform.io/hashicorp/aws v3.22.0

Affected Resource(s)

aws_db_proxy

Terraform Configuration Files

Please include all Terraform configurations required to reproduce the bug. Bug reports without a functional reproduction may be closed without investigation.

resource "aws_db_proxy" "my_proxy" {
  name                   = "my-proxy"
  debug_logging          = true
  engine_family          = "MYSQL"
  idle_client_timeout    = 1800
  require_tls            = false
  role_arn               = var.role_arn
  vpc_security_group_ids = var.proxy_security_group_ids
  vpc_subnet_ids         = var.db_subnet_ids
  auth {
    auth_scheme = "SECRETS"
    description = "example"
    iam_auth    = "DISABLED"
    secret_arn  = var.secret_arn
  }
}

Debug Output

https://gist.github.com/m-wynn/87aa1417f17ad36b1b165f70678c6874 The important part is 2021-01-07T12:03:25.362-0800 [DEBUG] plugin.terraform-provider-aws_v3.22.0_x5: caused by: Post "https://rds.us-east-1.amazonaws.com/": net/http: HTTP/1.x transport connection broken: too many transfer encodings: ["chunked" "chunked"]

Expected Behavior

The resource should be read. I can easily read this resource with aws-cli, e.g. aws rds describe-db-proxies --db-proxy-name my-proxy

Actual Behavior

The module hangs on trying to describe DB Proxies

Steps to Reproduce

I am unable to find the exact steps that led to the encodings being [“chunked” “chunked”]

same in west-us-2, reverted to 3.21.0 per @bgaillard above would be good to get an authoritative response on a plan to fix this issue, as were quite a way behind with this version…

Hey all, I have chatted to AWS Support about this and they have informed me that they have fixed this.

I have checked it on my end and I can now create an RDS Proxy via terraform using multiple auth blocks.

This morning I noticed that the error only happens on the latest versions of the terraform-provider-aws (3.22 and 3.23). I was unable to reproduce it with 3.20 and 3.21.

Briefly, this behavior is reproducible with our acceptance testing against us-west-2:

=== CONT  TestAccAWSDBProxy_basic
resource_aws_db_proxy_test.go:480: unexpected PreCheck error: RequestError: send request failed
caused by: Post "https://rds.us-west-2.amazonaws.com/": net/http: HTTP/1.x transport connection broken: too many transfer encodings: ["chunked" "chunked"]
--- FAIL: TestAccAWSDBProxy_basic (3096.76s)

Here’s the debug logging from the first invocation there:

We don’t do anything special in the aws_db_proxy resource as compared to other resources with regards to initializing or calling the AWS Go SDK receiver methods, and this has previously worked fine, so it may either be:

An issue with this particular AWS API after an API update
An issue that actually exists for all AWS Go SDK calls through the Terraform AWS Provider, but other AWS APIs ignore it and this API’s update now catches it
