First I execute the reindex
```auto
POST _reindex?wait_for_completion=false
{
"conflicts": "proceed",
"source": {
"index": "wh_crm_student_order_2020.11.09"
},
"dest": {
"index": "wh_crm_student_order_new_2020.11.09",
"version_type": "external"
}
}
```
reindex will return me 1 task ID which is yXafjEXKSu65EXqOuquJzg:2194095
Then I found that I couldn't find out the details of the task by the following request, the whole .task index is
```auto
GET /.tasks/_doc/yXafjEXKSu65EXqOuquJzg:2194095
```
But when I execute the following request, I can find the task I'm executing in all the tasks in the whole cluster, but I can't check only this one task by task ID, I want to understand why this happens, this situation is occasional
```auto
GET /_tasks
```

Try
`GET /_tasks/`
`GET /_tasks/yXafjEXKSu65EXqOuquJzg:2194095`

I tried it, my version is 7.4.2 and it returns the following
```auto
{
"error": "Incorrect HTTP method for uri [/.tasks/yXafjEXKSu65EXqOuquJzg:2194095?pretty] and method [GET], allowed: [POST]",
"status": 405
}
```
Need to use `GET /.tasks/_doc/yXafjEXKSu65EXqOuquJzg:2194095`
But this time, after I executed the reindex, I was able to get a new one by using `GET /.tasks/_doc/yXafjEXKSu65EXqOuquJzg:2194095` And did not check the task, But when the task is executed, after going to check, the task data can be successfully checked, I am wondering why this is?
Before the task is executed, I can be sure that the index .tasks is empty and there is no data

Same syntax in [7.4 Documents](https://www.elastic.co/guide/en/elasticsearch/reference/7.4/tasks.html)
You tried what command are you still putting the `.` in the command?
In general accessing the `.` (system indices) directly is not generally a good idea / not a supported API use at your own risk.
Directly from the 7.4 docs...
### Task management API
The task management API is new and should still be considered a beta feature. The API may change in ways that are not backwards compatible.
Returns information about the tasks currently executing in the cluster.
### Request
`GET /_tasks/`
`GET /_tasks`

Oh, my bad. It should be \_tasks and I wrote it as .tasks 。。。
