Error: AttributeError: 'User' object has no attribute 'title'

[spinnaker1]

I try to start the application locally.
I filled out: "API_ID", "API_HASH", "SESSION_String".

And "include_chats" = [1234567890] with my personal chat-id number. I used a bot called "RawDataBot" to fetch my chat-id.

It won't start and instead gives this error:
