错误：可能是未处理的承诺拒绝（ID：0）：凭据错误：配置中缺少凭据，如果使用AWS_CONFIG_FILE，请设置AWS_SDK_LOAD_CONFIG=1

我正在使用“aws-sdk”：在react原生（0.64.0）项目中的“^2.918.0”。我正在使用节点v14.17.0和Windows 10版本21 H1操作系统内部版本号19043.985运行该程序：

// Load the AWS SDK for Node.js
var AWS = require('aws-sdk');

AWS.config.update({
  region: 'us-east-1',
  maxRetries: 3,
  httpOptions: {timeout: 30000, connectTimeout: 5000},
});

// Create the DynamoDB service object
var ddb = new AWS.DynamoDB({
  apiVersion: '2012-08-10',
});

console.log('ddb: ', ddb);

~/.aws/配置

[default]
region=us-east-1
output=json

[profile myName]
region = us-east-1
output = json

~/.aws/凭证

[default]
aws_access_key_id=XXX...
aws_secret_access_key=XXX...

[mateo\.lara]
aws_access_key_id=XXX...
aws_secret_access_key=XXX...

当我使用ddb查询数据库时，尽管我已经在AWS CLI（aws-cli/2.2.6 Python/3.8.8 Windows/10 exe/AMD 64 prompt/off）中配置了我的凭据，但我还是收到了这个凭据错误。您知道可能是什么问题吗？如何解决？
------------------------------编辑-------------------
根据@nishkaush的建议，我尝试将AWS_SDK_LOAD_CONFIG=1添加到配置文件中，并尝试删除凭据文件并将aws_access_key_id和aws_secret_access_key添加到配置文件中，但均未成功。
下面是ddb日志的输出：
