ExAws: HTTP ERROR: :nxdomain for URL:

I’m using ExAws in my phoenix liveview project to call my S3 bucket. I tried running this code ExAws.S3.get_object("<bucketname>", "<objectkey>") |> ExAws.request!(region: "ap-southeast-1") in my iex getting this error:

ExAws: HTTP ERROR: :nxdomain for URL:

However, I know the URL is correct because I can put it into my browser to gain access to it. (Yes I set my bucket to public just to see if that was what’s blocking my request)

Here’s my config inside of config.exs:

# AWS
config :ex_aws,
  debug_requests: true,
  json_codec: Jason,
  access_key_id: {:system, "AWS_ACCESS_KEY_ID"},
  secret_access_key: {:system, "AWS_SECRET_ACCESS_KEY"}

Here’s my deps:

{:ex_aws, "~> 2.1"},
{:ex_aws_s3, "~> 2.0"},
{:hackney, "~> 1.9"},
{:sweet_xml, "~> 0.6"},
{:jason, "~> 1.2"},

My aws access key and secret access key are stored in the .env file in the root directory (side note: i dont know how to verify if the config is reading the .env variables correctly. I’m using dotenv to read fyi)

Can anyone please help provide me some guidance?
