我在lambda_handler.py中有一个简单的python脚本：

def handler(event, context):
    print("success")
    return "Success"

我把它打包在Docker中，以便在AWS Lambda上运行。
停靠文件为：

FROM public.ecr.aws/lambda/python:3.9

COPY lambda_handler.py ${LAMBDA_TASK_ROOT}

RUN yum install -y gcc-c++ pkgconfig poppler-cpp-devel
RUN pip install selenium boto3 --target "${LAMBDA_TASK_ROOT}"

CMD ["lambda_handler.handler"]

然而，当调用lambda时，我得到一个权限错误：

{
  "errorMessage": "[Errno 13] Permission denied: '/var/task/lambda_handler.py'",
  "errorType": "PermissionError",
  "requestId": "",
  "stackTrace": [

  ]
}
