Issue with Select Group Weights in ONOS JSON Configuration

[salmi sifeddine]

Hello everyone,

I'm currently working on setting up a Select Group in ONOS for load balancing, and I'm encountering an issue with specifying weights in the JSON configuration. When I include weights such as "weight": 0.3, I receive a server error with the message "at index 0." I've double-checked the syntax, but I'm still facing the problem.

Here's a simplified version of the JSON configuration:

{

  "type": "SELECT",

  "appCookie": "0x1234ABCD",
  "groupId": 1,
  "buckets": [
    {
      "weight": 0.4,
      "treatment": {
        "instructions": [
          {
            "type": "OUTPUT",
            "port": "2"
          }
        ]
      }
    },
    {
      "weight": 0.3,
      "treatment": {
        "instructions": [
          {
            "type": "OUTPUT",
            "port": "3"
          }
        ]
      }
    },
    {
      "weight": 0.3,
      "treatment": {
        "instructions": [
          {
            "type": "OUTPUT",
            "port": "4"
          }
        ]
      }
    }
  ]
}

I'm wondering if anyone in the community has encountered a similar issue or if there are specific considerations for specifying weights in ONOS JSON configurations for Select Groups. Any insights or suggestions would be greatly appreciated.

Thank you in advance!
