[sanknmFinicity]

Expected behavior

We have field defined in mongoose

feild1: [
{
type: Schema.Types.Mixed,
validate: customValidatior,
default: customDefaultFeild,
},
]

In V4 version , feild1 is getting that is getting mapped in following manner in .forestadmin-schema.json

"field": "feild1",
      "type": [{
        "fields": [{
          "field": "validate",
          "type": {
            "fields": []
          }
        }, {
          "field": "default",
          "type": [{
            "fields": []
          }]
        }]
      }],

In V6 version .forestadmin-schema.json
{
"field": "feild1",
"type": [null],
"defaultValue": null,
}
