该错误通常表示 AWS Secrets Manager 凭据中的访问密钥 ID 和密钥不正确或未被正确配置。为了解决此问题，您可以尝试使用正确的凭据，或检查您的权限，以确保您有权限访问凭据。此外，请确保您的 AWS Secrets Manager 客户端配置正确，并且您正在使用更新的版本。以下是一个示例代码，演示如何正确地获取凭据并对其进行访问：

import boto3
from botocore.exceptions import ClientError

def get_secret():
    secret_name = "my_secret_name"
    region_name = "my_region"
    
    # Create a Secrets Manager client
    session = boto3.session.Session()
    client = session.client(
        service_name='secretsmanager',
        region_name=region_name
    )

    # Get the secret value
    try:
        response = client.get_secret_value(SecretId=secret_name)
    except ClientError as e:
        if e.response['Error']['Code'] == 'DecryptionFailureException':
            # Secrets Manager can't decrypt the protected secret text using the provided KMS key.
            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
        elif e.response['Error']['Code'] == 'InternalServiceErrorException':
            # An error occurred on the server side.
            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
        elif e.response['Error']['Code'] == 'InvalidParameterException':
            # You provided an invalid parameter value.
            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
        elif e.response['Error']['Code'] == 'InvalidRequestException':
            # You provided a parameter value that is not valid for the current state of the resource.
            # Deal with the exception here, and/or rethrow at your discretion.
            raise e
        elif e.response['Error']['Code'] == 'ResourceNotFoundException':
            # We can't find the resource that you asked for.
            # Deal with the exception here,
