Hi @divyeshgajja - An issue is already opened for this particular problem, see #540.

I had a similar problem when I was sending this request:

{
    "status": "ENABLED",
    "resource_name": "customers/1310914546/adGroupAds/138411489117~-1",
    "ad": {
         // ... ad data...
    }
}

I got thie error:

{
  "errors": [
    {
      "error_code": {
        "collection_size_error": "TOO_FEW"
      },
      "message": "Too few.",
      "location": {
        "field_path_elements": [
          {
            "field_name": "operations",
            "index": 0
          },
          {
            "field_name": "create"
          },
          {
            "field_name": "ad"
          },
          {
            "field_name": "responsive_display_ad"
          }
        ]
      }
    }
  ],
  "request_id": "mgwfdaAiCjDqvtX71qFfSQ"
}

I've contacted the adwords forum as @fiboknacky recommanded and they were fast and helpful.

In my case, it was because my resource_name ended with a -1 and such endings were saved for mutations and batch requests. Replacing the resource_name with an ad_group with a correct path resolved it for me.
