ArgumentError: broadcasting over dictionaries and `NamedTuple`s is reserved when loading image in Julia

Question

I am trying to load an image using images. I get the following error:

Error showing value of type Array{RGBA{Normed{UInt8,8}},2}:
ERROR: ArgumentError: broadcasting over dictionaries and `NamedTuple`s is reserved

I call

julia> using FileIO
julia> using Images
julia> img_holder = load("zone-map.png")
Error showing value of type Array{RGBA{Normed{UInt8,8}},2}:
ERROR: ArgumentError: broadcasting over dictionaries and `NamedTuple`s is reserved
Stacktrace: etc. etc. etc. 

Any thoughts on how to fix that?

Edit: I am getting the same error when I run the example from here: https://juliaimages.org/latest/function_reference/#ImageTransformations.imresize

So, maybe there's something wrong with my install? Here is the full stack track:

This happens when there's a mismatch between the version of Atom.jl and julia-client (the Atom package).

Please make sure you're on at least v0.11.0 of Atom.jl when using julia-client 0.11.x -- it's a good idea to match minor versions in general. You should also be getting a warning like this:
