I tried to resolve myself but i cannot the problem showing, the chat is not storing, everytime the chat screen opening without old chats. I also need contact name with number I tried it myself but the problem is showing: length of list is too large. Please tell me what to do, google is not giving appropriate solution.

It does not make much sense to use a join block here, does it?
Remove it and use only one length of list block together with one of the lists…
