[Open API 3.1] Json31 is incorrectly assuming that property containing anyOf is of type: object

[daniel-urrutia]

Using Json31.pretty() I'm getting back properties with anyOf containing "type": "object"

"image" : {
      "type" : "object",
      "anyOf" : [ {
        "type" : "string"
      }, {
        "type" : "null"
      } ],
      "title" : "Image"
    },

but this doesn't match my schema below, image doesn't contain "type": "object" :

"PreviewProduct": {
        "properties": {
          "id": {
            "type": "string",
