From the JSONSchema community Slack -->

One thing I noticed is invalid use of oneOf on this line. https://github.com/o19s/ubi/blob/main/schema%2F1.0.0%2Fquery.response.schema.json#L11
JSON Schema validation does not evaluate the format keyword to distinguish strings. The format keyword is referred to as an annotation and is only informational.
You might try something like this.

{
  "query_id": { 
    "type": "string",
    "oneOf":[
      { "pattern": "pattern for <uuid>"},
      {"not":{ "pattern": "pattern for <uuid>", "maxLength": 100}}
    ]
  }
}
