Landsat 8 cloud masking example not working

The last part is failing, specifically:

getThumbURL(composite, Dict(
    :bands => "B7,B5,B3",
    :min => 0.05,
    :max => 0.55,
    :gamma => 1.5,
    :region => region,
    :dimensions => 1024
))

The error is:

WARNING: both EarthEngine and Base export "Dict"; uses of it in module Main must be qualified
ERROR: UndefVarError: `Dict` not defined
Stacktrace:
 [1] top-level scope
   @ ~/DataSci/LandsatComposites/composite.jl:55

Using the following:

getThumbURL(composite, EarthEngine.Dict(
    :bands => "B7,B5,B3",
    :min => 0.05,
    :max => 0.55,
    :gamma => 1.5,
    :region => region,
    :dimensions => 1024
))

gives the following python error:

ERROR: PyError ($(Expr(:escape, :(ccall(#= /home/tpoisot/.julia/packages/PyCall/ilqDX/src/pyfncall.jl:43 =# @pysym(:PyObject_Call), PyPtr, (PyPtr, PyPtr, PyPtr), o, pyargsptr, kw))))) <class 'TypeError'>
