Is there a way to stop the error that occurs in Kibana (v8.3.2)?

I am building the following environment on a local server.
・ Kibana: 8.3.2
・ Elsticsearch: 8.3.2 (Basic license)
When I started the above two services with systemd, it started without any problem, but when I checked the log, the following error was written in kibana.log.

  "ecs": {
    "version": "8.0.0"
  "@timestamp": "2022-07-25T16:07:58.076+09:00",
  "message": "Task ML:saved-objects-sync \"ML:saved-objects-sync-task\" failed: ResponseError: {\"error\":\"Incorrect HTTP method for uri [/_ml/anomaly_detectors] and method [GET], allowed: [POST]\",\"status\":405}",
  "log": {
    "level": "ERROR",
    "logger": "plugins.taskManager"
  "process": {
    "pid": 2685
  "trace": {
    "id": "0f337104bf927519d50fedbb3a4a5730"
  "transaction": {
    "id": "095d566b7aef7f77"

The above log is generated every hour because it is due to a task executed on the kibana server side.
I also think this task is related to machine learning.
However, elasticsearch.yml on the Elasticsearch server to which kibana is connected has the following settings. false

For this reason, elasticsearch does not accept APIs related to machine learning, so we expect the above logs to occur.

In Kibana of v7.14 that I used before, the above log did not occur.
Please tell me how to resolve this error.

@James_Gowdy, would you be able to help out with this?
