Invalid escape sequence


I’m studying Genie from the example in
When I was trying connect SearchLight to DB, using the following command:
julia> SearchLight.Configuration.load_db_connection() |> SearchLight.Database.connect!

it kept having problem saying:

ERROR: Base.Meta.ParseError(“invalid escape sequence”)

[2] #parse at .\none:0 [inlined]

[7] connect!(::Dict{String,Any}) at C:\Users\19652.julia\packages\SearchLight\JA5Zc\src\Database.jl:53
[8] top-level scope at none:0

Does anyone know how to fix it?
