Document is misleading for the zip_file option of Aws::Lambda::Client#update_function_code

[ShikChen]

The document says:

:zip_file (IO, String) — Based64-encoded .zip file containing your packaged source code.

But in fact you should not encode your zip file in Base64. The raw string of zip file just works.

You do not need to encode to base64. We are using

IO.read(path_to_zip)

Thank you for reporting this issue. Currently we generate our API documentation from the same source as the service API reference. This means that sometimes HTTP wire-level documentation sneaks into the SDK documentation. The SDK will automatically base64 encode data that is to be treated as a binary blob.

I'll see what we can do about improving the SDK documentation to not mention the encoding.
