Python 3.x AWS SAM计划Lambda未按照计划触发

我有一个用例，我需要每2分钟调用一个API来检查更新并将结果存储到数据库中。同样，我正在尝试使用AWS SAM CLI和Python实现AWS Schedule lambda函数，但是我的lambda函数没有被触发。下面是我的代码：

app.py

def lambda_schedule(event, context):
    print("Lambda Schedule event started Successfully......")
    print("Lambda function ARN:", context.invoked_function_arn)
    print("CloudWatch log stream name:", context.log_stream_name)
    print("CloudWatch log group name:", context.log_group_name)
    print("Lambda Request ID:", context.aws_request_id)
    print("Lambda Schedule event ended Successfully......")

def lambda_schedule(event, context):
    print("Lambda Schedule event started Successfully......")
    print("Lambda function ARN:", context.invoked_function_arn)
    print("CloudWatch log stream name:", context.log_stream_name)
    print("CloudWatch log group name:", context.log_group_name)
    print("Lambda Request ID:", context.aws_request_id)
    print("Lambda Schedule event ended Successfully......")

模板yaml

              - "aws.events"

    Properties:

有谁能告诉我，我的代码中有什么错误或缺少什么吗？

我犯了错误。许可部分有错误。我在这里发布了正确的yaml配置，以便对AWS SAM CLI新手有所帮助

app.py

def lambda_schedule(event, context):
    print("Lambda Schedule event started Successfully......")
    print("Lambda function ARN:", context.invoked_function_arn)
    print("CloudWatch log stream name:", context.log_stream_name)
    print("CloudWatch log group name:", context.log_group_name)
    print("Lambda Request ID:", context.aws_request_id)
    print("Lambda Schedule event ended Successfully......")

def lambda_schedule(event, context):
    print("Lambda Schedule event started Successfully......")
    print("Lambda function ARN:", context.invoked_function_arn)
    print("CloudWatch log stream name:", context.log_stream_name)
    print("CloudWatch log group name:", context.log_group_name)
    print("Lambda Request ID:", context.aws_request_id)
    print("Lambda Schedule event ended Successfully......")
