com.google.gson.JsonSyntaxException when deserialize V1Secret json which returned by the api

V1Secret.data is the Map<String, byte[]>, but the CoreV1Api return the json like: "data":{"test1":"ZEdWemRHUmhkR0V4","test2":"ZEdWemRHUmhkR0V5"}

It can not be handled by the com.google.gson.internal.bind.ArrayTypeAdapter, the stack trace is:

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was STRING at line 1 column 284 path $.data.

If the temporary workaround were put into the real source, it would look something like the diff below. Of course, the JSON code uses TypeAdapters instead of JsonSerializer and JsonDeserializer so it is probably not the correct change.

• private ByteArrayBase64StringTypeAdapter base64TypeAdapter = new ByteArrayBase64StringTypeAdapter();

  public JSON() { gson = new GsonBuilder() @@ -48,6 +47,7 @@ public class JSON { .registerTypeAdapter(java.sql.Date.class, sqlDateTypeAdapter) .registerTypeAdapter(DateTime.class, dateTimeTypeAdapter) .registerTypeAdapter(LocalDate.class, localDateTypeAdapter)

•        .registerTypeAdapter(byte[].class, base64TypeAdapter)
         .create();
  

  }

• /**

• * Gson TypeAdapter for byte[] type
  

• */
  

• public static class ByteArrayBase64StringTypeAdapter implements JsonSerializer<byte[]>, JsonDeserializer<byte[]> {

•    public byte[] deserialize(JsonElement json, Type typeOfT, JsonDeserializationContext context) throws JsonParseException {
  

•        return Base64.getDecoder().decode(json.getAsString());
  

•    }
  

•    public JsonElement serialize(byte[] src, Type typeOfSrc, JsonSerializationContext context) {
  

•        return new JsonPrimitive(Base64.getEncoder().encodeToString(src));
  

•    }
  

• }

Re-opening this, the correct fix is in #219
