@alex-dixon Yeah looks like this is the offending property. I haven't seen this schema variation for defining an array of enums, I would expect this:

{
    "type": "array",
    "items": {
        "type": "string",
        "enum": ["ALL_SUBNETS"]
    }
}

How sure are we its valid schema? can't seem to find examples like this.

This issue has not received a response in a while and will be closed soon. If you want to keep it open, please leave a comment below @mentioning a maintainer.

Good point...
Maybe the intent was this?

  "type": "array",
  "items": {
    "type": "string",
    "enum": [
     "ALL_SUBNETS"
    ], 
  }

The original seems valid yet unsatisfiable?

Keeping this open and marking p2. We need to investigate if that enum declaration is indeed a valid JSON schema - if so we will fix it. If not - not.
