Please format your code/logs/config using the `</>` button, or markdown style back ticks. It helps to make things easy to read which helps us help you 🙂

What version are you on? I just tried your first `PUT` and got;

```auto
{
  "error" : {
    "root_cause" : [
      {
        "type" : "mapper_parsing_exception",
        "reason" : "Root mapping definition has unsupported parameters: [info : {_routing={required=true}, properties={cust_no={type=keyword}}}]"
      }
    ],
    "type" : "mapper_parsing_exception",
    "reason" : "Failed to parse mapping [_doc]: Root mapping definition has unsupported parameters: [info : {_routing={required=true}, properties={cust_no={type=keyword}}}]",
    "caused_by" : {
      "type" : "mapper_parsing_exception",
      "reason" : "Root mapping definition has unsupported parameters: [info : {_routing={required=true}, properties={cust_no={type=keyword}}}]"
    }
  },
  "status" : 400
}

```
