Can't perform TLRequestMessagesGetFullChat #71

Closed comrados closed 6 years ago

comrados commented 6 years ago

When I try to get full information about chat (TLRequestMessagesGetFullChat), I get a deserialization error:

The same GetFull requests work fine for Channels and Users (but they also require access hashes).

It tries to cast TLChatInviteEmpty to TLChatInviteExported but not to TLAbsChatInvite.

int chatID = 0; // some chat ID here
TLRequestMessagesGetFullChat fullRequest = new TLRequestMessagesGetFullChat();
fullRequest.setChatId(chatID);
                try {
                    TLAbsChatFull fullDialog = api.doRpcCall(fullRequest);
                } catch (RpcException e) {
                    System.err.println(e.getErrorTag() + " " + e.getErrorCode());
                } catch (TimeoutException | IOException e) {
                    System.err.println(e.getMessage());
                }

Errors:
