Admin user privileges to access to PUT /.plugins-ml-config/_doc/os_chat

OpenSearch
1

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser): Opensearch 2.19.1

Describe the issue:
we created mistral ai agent on model, and would like to perform
PUT /.plugins-ml-config/_doc/os_chat
{
“type”:“os_chat_root_agent”,
“configuration”:{
“agent_id”: “kPQygZoBA2ag4AIKsaL4”
}
}

this command so we can integrate this agent with Opensearch dashboard AI assistant.

but to proceed with this command we are facing error:

{
“error”: {
“root_cause”: [
{
“type”: “security_exception”,
“reason”: “no permissions for and User [name=admin, backend_roles=[admin], requestedTenant=]”
}
],
“type”: “security_exception”,
“reason”: “no permissions for and User [name=admin, backend_roles=[admin], requestedTenant=]”
},
“status”: 403
}

so could someone suggest a way to resolve this?

@amolusare have you disabled the security protection using the following:

PUT /_cluster/settings
{
    "persistent": {
        "plugins.ml_commons.connector_access_control_enabled": false
    }
}
