The authorization header is malformed; a non-empty Access Key (AKID) must be provided in the credential.

Environment

• Elixir version 1.14 & Erlang version 24
• ExAws version 2.5.0
• HTTP client version 1.18.1

Current behavior

Mostly failed to read/upload files but after retrying 3/4 times it works and reads files.

Sample code to read file:

ExAws.S3.get_object("project-assets", "yallo-gjuyq/ealog-jxsyr.png") |> ExAws.request()

Expected behaviour

It should read/write the file on the first attempt.

That's weird. What's your config look like (with keys redacted, obviously)? Because it works fine for plenty of people so there must be something specifically weird in your setup.

[azharmalik3]

It worked fine before the update to the latest version (2.5.5) and used the same config.

config :ex_aws,
  access_key_id: System.fetch_env!("AWS_ACCESS_KEY_ID"),
  secret_access_key: System.fetch_env!("SECRET_ACCESS_KEY"),
  region: "eu-west-1",
  json_codec: Jason

Then we revert back the version to 2.4.4 and it works.
