无法使用 lambda 函数将视频上传到 s3 Lambda 代码调用 lambda 的本地系统代码

如何解决无法使用 lambda 函数将视频上传到 s3 Lambda 代码调用 lambda 的本地系统代码

我正在尝试通过 lambda 函数将不同格式的文件上传到 s3 存储桶，为此，我在本地系统中对文件进行编码，然后在 lambda 中对文件进行解码并将其保存在 s3 中

Lambda 代码

import boto3
import base64

def lambda_handler(event,context):
    
    encoded_data=event["content"]
    
    decoded_string =base64.b64decode(encoded_data)
  
    
    file_name=event['file_name']

    bucket_name = "xxxx"
    lambda_path = "/tmp/" + file_name
    s3_path = "xxxx-data/xxx-videos/" + file_name

    s3 = boto3.resource("s3")
    s3.Bucket(bucket_name).put_object(Key=s3_path,Body=decoded_string)

调用 lambda 的本地系统代码

import base64
import requests
import json

with open("21.mp4","rb") as video_file:
    encoded_string = base64.b64encode(video_file.read())

text= encoded_string.decode('utf-8')
    
body = {"content":text,"file_name":"21.mp4"}

headers= { "Access-Control-Allow-Origin": "*","Content-Type": "application/json" }

r1 = requests.post(aws_lambda_url,data=json.dumps(body),headers=headers)

我可以上传 pdf、图像文件，但在上传视频文件时出现以下错误，如何解决此错误？
