sdk does not seem to be retrieving aws bedrock credentials correctly

[armando-swarm]

1. the templates do not seem to provide aws_access_key aws_secret_key and aws_region being expected by the amazon_bedrock_request function in utils.py. if you look at the llm_kwargs field of a template you get

{
    "messages": [
      {
        "role": "user",
        "content": []
      }
    ],
    "system": [
      {
        "text": "Your prompt",
      }
    ],
    "modelId": "us.anthropic.claude-sonnet-4-20250514-v1:0",
    "inferenceConfig": {
      "topP": 1,
      "temperature": 0,
      "maxTokens": 1024
    }
  }

2. the boto client inside utils.py cannot completely take the configuration from your aws credentials file because region always defaults to us-east-1. If you have your bedrock in another region the sdk will never work. this is caused by the following line which defaults to us-east-1 if region is not provided by the template

region_name=function_kwargs.pop("aws_region", "us-east-1"),
