boto3 - Boto3 Guard Duty Put Target 在执行时出错

Question

我正在为 Cloudwatch 规则创建 boto3，当我使用 client.put_targets 函数时出现以下错误。

https://boto3.amazonaws.com/v1/documentation/api/1.9.42/reference/services/events.html#CloudWatchEvents.Client.put_targets

raise error_class(parsed_response, operation_name)
botocore.exceptions.ClientError: An error occurred (ValidationException) when calling the PutTargets operation: Invalid InputTemplate for target GuardDuty : [Source: (String)"null is in region null"; line: 1, column: 8].

这是代码的样子

client.put_targets(Rule='GuardDutyAlarm',
                   Targets=[{'Id': 'GuardDuty',
                             'Arn': 'arn:aws:sns:us-west-2:****:GuardDutyAlarmTeams',
                             'InputTransformer': {
                                 'InputPathsMap': {'severity': '$.detail.severity', 'region': '$.region'},
                                 'InputTemplate': "<severity> is in region <region>"}}])

我们遇到了类似的问题，我们找到了解决方法。你必须做这样的事情

client.put_targets(Rule='GuardDutyAlarm',
                   Targets=[{'Id': 'GuardDuty',
                             'Arn': 'arn:aws:sns:us-west-2:****:GuardDutyAlarmTeams',
                             'InputTransformer': {
'InputPathsMap': {'severity': '$.detail.severity', 'region': '$.region'},
'InputTemplate': "\" <severity> is in region <region>  \"\n" }}])
