Amazon web services Boto3 DMS'；修改复制任务'；复制任务设置出错

我正在使用boto3创建DMS复制任务。我正在使用以下

replication\u task\u settings.json

创建复制任务：

调用

dms\u客户机时，上面的JSON可以正常工作。创建\u复制\u任务

。但是，在修改复制任务时，它不起作用

调用上面提到的

replication\u task\u settings.json

时，调用

dms\u client.modify\u replication\u task

会出现以下错误：

botocore.exceptions.ClientError:调用ModifyReplicationTask操作时发生错误（InvalidParameterValueException）：任务设置无效

我不知道为什么会发生这种情况，任何帮助都将不胜感激

我尝试删除一些已经默认的设置。我试图寻找格式错误的JSON，但没有明显的结果

---

我希望

replication\u task\u设置json

可以用于创建和修改DMS复制任务。

我在尝试使用CLI修改复制任务时遇到类似问题：

aws --profile non-prod dms modify-replication-task --replication-task-arn arn:aws:dms:ap-southeast-3:567384657322:task:ABC --replication-task-settings file:/json_task --region ap-southeast-3

这是错误：

aws --profile non-prod dms modify-replication-task --replication-task-arn arn:aws:dms:ap-southeast-3:567384657322:task:ABC --replication-task-settings file://json_task --region ap-southeast-3

调用时发生错误（InvalidParameterValueException） ModifyReplicationTask操作：无效的任务设置

以下命令有效：

aws --profile non-prod dms modify-replication-task --replication-task-arn arn:aws:dms:ap-southeast-3:567384657322:task:ABC --replication-task-settings file://json_task --region ap-southeast-3

更改是在JSON文件名之前使用两个“/”来修改任务
