Derivative name in file name

I add #generate_location(io, context) method to change file name and wanted to add derivative name to path.

When creating derivative in cache storage context receives value for example {derivative: :thumb}
But when promoting - {derivative: [:thumb]} (array value)

Distiction is in this to methods, where one uses derivative_path(path)

def upload_derivatives(files, **options)
  map_derivative(files) do |path, file|
    path = derivative_path(path)


    upload_derivative(path, file, **options)
  end
end

def promote_derivatives(**options)
  stored_derivatives = map_derivative(derivatives) do |path, derivative|
    if cached?(derivative)
      upload_derivative(path, derivative, **options)
    else
      derivative
    end
  end

Hi, thanks for reporting and finding the root cause. I’ve just pushed a fix to master.
