NSInvalidArgumentException key cannot be nil

Thanks for building this app, it's the only safe way to migrate chats from Android to iPhone!

When trying to migrate my chats, I get the following error:

2021-11-14 22:22:46.122 watoi[7909:101018] 	 is group chat

It looks like a null check, is there a quick fix for this?

Adding an if check around memberJID seemed to work, although now all chat messages do not have a name associated to them...

    if (memberJID) {
      [member setValue:chat forKey:@"chatSession"];
      [members setObject:member forKey:memberJID];
    }
