我有这个案例课：
case class CodeRegister(id: String, name: String, code: Option[CodeData])
case class CodeData(code: String, expiry: Long)
我已经通过CodeRegister方法注册了CodeData和fromProviders。现在，我尝试使用此代码更新字段code
collection.updateOne(equal("id",record. id),
set("code", record.code)).
toFutureOption()
但是，我遇到了这个错误

我通过添加SomeCodec并在CodeData上添加了新的匹配条件，来尝试了this link中的解决方案，
case Some(v: CodeData) => {
writer.writeStartDocument()
writer.writeString(v.code)
writer.writeInt64(v.expire)
writer.writeEndDocument()
}
但是我遇到了这个错误
org.bson.BsonInvalidOperationException: writeString can only be called when State is VALUE, not when State is NAME
现在，我不知道下一步该怎么做。任何帮助表示赞赏。
