使用以下代码将大文件从 S3 (>5GB) 读取到 lambda 中：

import json
import boto3

s3 = boto3.client('s3')

def lambda_handler(event, context):
    
    response = s3.get_object(
        Bucket="my-bucket",
        Key="my-key"
    )
    
    text_bytes = response['Body'].read()

    ...
    
    return {
        'statusCode': 200,
        'body': json.dumps('Hello from Lambda!')
    }

但是我收到以下错误：

"errorMessage": "signed integer is greater than maximum"
"errorType": "OverflowError"
"stackTrace": [
