可能会出现不能设置AWS Secrets Manager中的权限的情况。以下是一个示例代码，说明如何解决这个问题：

import boto3
from botocore.exceptions import ClientError

def add_secret_permissions(secret_name, role_name, region_name, permission):
    """
    Adds permission to a secret for a specific AWS IAM role.

    :param secret_name: The name of the secret.
    :param role_name: The name of the AWS IAM role to grant access to the secret.
    :param region_name: The AWS region where the secret is stored.
    :param permission: The permission to grant. Can be 'ReadWrite' or 'ReadOnly'.
    :return: True if permission was granted, False otherwise.
    """

    # Create a new Secrets Manager client
    client = boto3.client('secretsmanager', region_name=region_name)

    # Define the policy to grant permission to the specified role
    policy = {
        "Version": "2012-10-17",
        "Statement": [
            {
                "Effect": "Allow",

                }
            }
        ]
    }

    # Grant permission based on the specified type
    if permission == 'ReadWrite':
        try:
            response = client.put_secret_policy(
                SecretId=secret_name,
                ResourcePolicy=policy,
                BlockPublicPolicy=True
            )
        except ClientError as e:
            print("Error occurred while adding secret permission: ", e)
            return False
    elif permission == 'ReadOnly':
        try:
