Python用boto3从代码中调用我的AWS lambda

Question

在我的项目中，我必须创建一个py来调用lambda函数来传递body参数，我编写了以下代码：

import boto3
import json
import base64

client = boto3.client(‘lambda’)
d = {'calID': '92dqiss5bg87etcqeeamlmob2g@group.calendar.google.com', 'datada': '2017-12-22T16:40:00+01:00', 'dataa': '2017-12-22T17:55:00+01:00', 'email': 'example@hotmail.com'}
s = json.dump(d)
s64 = base64.b64encode(s.encode('utf-8'))

response = client.invoke(
    FunctionName='arn:aws:lambda:eu-west-1:13737373737:function:test',
    InvocationType='RequestResponse',
    LogType='None',
    ClientContext='None',
    Payload=s64
)

但当响应运行时，将生成此错误：

InvalidRequestContentException: An error occurred (InvalidRequestContentException) when calling the Invoke operation: Could not parse request body into json: Unrecognized token 'eyJjYWxJRCI6ICI5MmRxaXNzNWJnODdldGNxZWVhbWxtb2IyZ0Bncm91cC5jYWxlbmRhci5nb29nbGUuY29tIiwgImRhdGFkYSI6ICIyMDE3LTEyLTIyVDE2OjQwOjAwKzAxOjAwIiwgImRhdGFhIjogIjIwMTctMTItMjJUMTc6NTU6MDArMDE6MDAiLCAiZW1haWwiOiAibHVjYV9ncmV6eml4eEBob3RtYWlsLmNvbSJ9': was expecting ('true', 'false' or 'null') at [Source: [B@4587098d; line: 1, column: 481]

这是什么意思？
