Working lambda function with s3 code doesn't work with plugin

从 /var/task/helpers/s3_helper.rb 中的 S3 require 以及经过 handlers/base_handlers/pg_handler.rb 和 handlers/void_charge.rb 的 require 链开始。使用 Ruby 3.2.2 和 serverless.yml 中的插件配置重现部署，然后追踪插件启用时 aws-sigv4 不可用的原因。当加载 S3 的函数能够通过 Datadog wrapper 成功调用，并且不访问 S3 的函数仍能正常工作时，即视为完成。

Expected Behavior

running lambda can add datadog wrapper with no issues

Actual Behavior

once I add the plugin, without adding instrumenting code, running lambdas that involve loading content from s3 fails with below error

"errorMessage": "cannot load such file -- aws-sigv4",
  "errorType": "Init<LoadError>"

Functions that do not load s3 files runs with no error.
The s3 code

      s3_object = s3.get_object({bucket: ENV['S3_BUCKET_NAME'], key: '*****'})
      file_contents = s3_object[:body].read
      application_file = YAML.load(file_contents)

Steps to Reproduce the Problem

1. Add below to serverless.yml

+  - serverless-plugin-datadog 
 custom:
+  datadog:
+    site: datadoghq.com
+    apiKeySecretArn: ********

2. deploy and invoke function

Specifications

• Serverless Framework version: 3.22.0
• Datadog Serverless Plugin version: 5.89.0
• Lambda function runtime (Python 3.7, Node 10, etc.): Ruby 3.2.2
