How to migrate files from local persistent storage with CarrierWave correctly?

[afuno]

Initially, the application used local persistent storage. I tried moving the entire uploads directory into ImageKit. I kept the previous configuration and added a new one from ImageKit:

class BaseUploader < CarrierWave::Uploader::Base
 include ImageKitIo::CarrierWave

 def store_dir
 full_file_path
 end

 # ...

 def options
 {
 response_fields: "isPrivateFile, tags",
 tags: %w[images],
 use_unique_file_name: false,
 folder: full_file_path
 }
 end

 private

 # ...

 def full_file_path
 "uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{dirs}"
 end

 # ...
end

As a result I get this error:

unexpected token at 'f1843b5f9.jpg'

From this line:

= image_tag band.card_image.url

In this case, the full name of the file in the database is: 9757131f1843b5f9.jpg.

Please tell me what else needs to be done to migrate files?

This error comes from this place:

carrierwave/storage/ik_file.rb

def initialize(identifier)
 @identifier=JSON.parse(identifier)
 @imagekit = ImageKitIo.client
end

The variable identifier has the value 9757131f1843b5f9.jpg.
