Nested map of a pojo with Jackson

Question

I understand that I can create a map of a specified object with Jackson by using TypeReference. For instance, taking a class ...

public class Error {    
    /** Error code */
    private final String errcode;
    /** Error message */
    private final String error; 
// Getter
}

... and the data in JSON

{
   "firstError":{
      "errcode":"1234",
      "error":"The 1. message"
   },
   "secondError":{
      "errcode":"5678",
      "error":"The 2. message"
   }
}

... I can deserialize with

TypeReference<HashMap<String, Error>> typeRef  = new TypeReference<HashMap<String, Error>>() {};
Map<String, Error> map = new ObjectMapper().readValue(jsonInput, typeRef);

My question is now: What can I do if my JSON looks like this?

{
   "date":"2022-01-01",
   "server":"myfancyserver",
   "errors":{
      "firstError":{
         "errcode":"1234",
         "error":"The 1. message"
      },
      "secondError":{
         "errcode":"5678",
         "error":"The 2. message"
      }
   }
}
