Packetbeat does not point to a write index

[TheHunter1]

Hello,

I tried to edit packetbeat Policy, and then from index management on Kibana I removed the policy from that index and then added it again (to take on consideration the new configuration),
unfortunately I a getting a lifecycle error

illegal_argument_exception: rollover target [packetbeat-7.9.2] does not point to a write index

I tried to run :

PUT packetbeat-7.9.2-2020.11.17-000002
{
  "aliases": {
    "packetbeat-7.9.2": {
      "is_write_index": true
    }
  }
}

But I got the error:

{
  "error" : {
    "root_cause" : [
      {
        "type" : "resource_already_exists_exception",
        "reason" : "index [packetbeat-7.9.2-2020.11.17-000002/oIsVi0TVS4WHHwoh4qgyPg] already exists",
        "index_uuid" : "oIsVi0TVS4WHHwoh4qgyPg",
        "index" : "packetbeat-7.9.2-2020.11.17-000002"
      }
    ],
    "type" : "resource_already_exists_exception",
    "reason" : "index [packetbeat-7.9.2-2020.11.17-000002/oIsVi0TVS4WHHwoh4qgyPg] already exists",
    "index_uuid" : "oIsVi0TVS4WHHwoh4qgyPg",
    "index" : "packetbeat-7.9.2-2020.11.17-000002"
  },
  "status" : 400
}
