unexpected generation of type

[sqs]

The following JSON Schema triggers a bug in the compiler. It emits an Args-typed field but there is no type definition of Args.

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "additionalProperties": false,
  "properties": {
    "args": {
      "type": "object",
      // Adding this line fixes it:
      //
      // "additionalProperties": true
    }
  }
}
