File uploader component not working in Genie Builder

[PGimenez]

I'm trying to add the uploader component to GB, but when using it inside of GB it does not work. The file is not uploaded and the following exception is thrown:

┌ Error: 2024-05-31 14:08:13 Error processing file: Base.IOError("open(\"/var/folders/h_/l8hxc31x73s97400gprpwnr80000gn/T/jl_Yxe327A5U9\", 0, 0): no such file or directory (ENOENT)", -2)
└ @ Main ~/genie/mwes/CSVUploader/app.jl:19

It works fine when running the app from the terminal outside GB.

Here's the code I'm testing with:

 using GenieFramework
@genietools

const FILE_PATH = joinpath("public", "uploads")
mkpath(FILE_PATH)

@app begin
    @onchange fileuploads begin
        @show fileuploads
        if ! isempty(fileuploads)
            @info "File was uploaded: " fileuploads
            notify(__model__,"File was uploaded: $(fileuploads)")
            filename = fileuploads["name"]

            try
                isdir(FILE_PATH) || mkpath(FILE_PATH)
                mv(fileuploads["path"], joinpath(FILE_PATH, filename), force=true)
            catch e
                @error "Error processing file: $e"
                notify(__model__,"Error processing file: $(fileuploads["name"])")
            end

            fileuploads = Dict{AbstractString,AbstractString}()
        end
        upfiles = readdir(FILE_PATH)
    end



end
