Hi,
I have mysql data field. My data field name is 'islem'. This field deault value is 'Y'. For example:
islem='Y'
islem='YI'
islem='YS'
islem='YDS'
islem='YS'
islem='YD'
islem='YDDDD'
islem='YDDDDS'.. etc

I did nested mapping this field name on sense editor. Because It has to be unique array on my php index codes.

PUT ihaleler/ihale/_mapping
{
  "properties": {
    "islem": {
      "type": "nested"
    } } }

After I indexed this field with php codes. But ı has error:

Fatal error:  Uncaught exception 
'Guzzle\Http\Exception\ClientErrorResponseException' with message
