Hello everyone,
Firstly, have a nice day  

Secondly, I have deployed E-Services Solution on my individual lab. Be honest, I have been encountering so many isssues. 
I Installed E-mail, Chat, SMS and WebAPI server on my solution; however, I just E-mail work correctly.
I tried to test chat service via WebAPI. So, there are errors flush in chat_log and interaction_log belows:
[chat_log]:
