LocalDateTime can't serialized to json

[xmt328]

I try to use ItemUpdateApi#updateItem(itemId: UUID, data: BaseItemDto)

but an error occurred

{
   "type":"https://tools.ietf.org/html/rfc7231#section-6.5.1",
   "title":"One or more validation errors occurred.",
   "status":400,
   "traceId":"00-33dd05cfdb47ed4088bf0ae90b8b86da-8b9f9586acc83544-00",
   "errors":{
      "request":[
         "The request field is required."
      ],
      "$.DateCreated":[
         "The JSON value could not be converted to System.DateTime. Path: $ | LineNumber: 0 | BytePositionInLine: 52. Path: $.DateCreated | LineNumber: 0 | BytePositionInLine: 268."
      ]
   }
}

I made a pull request that should fix this issue (#287). When it's merged you can test it by using a snapshot version of the SDK (instructions in the README). You can also manually clone the pull request and run the publishToMavenLocal gradle task, then in your app add the mavenLocal() repository and change the SDK version to latest-SNAPSHOT.
