"group_id is invalid" error

[vipulnsward]

Describe the bug

When they uploading more then 10 files we get a "group_id is invalid" error.

Works well with 5 files.

After submitting the form, url is being saved in the model

# UploadcareDocument (with mount_uploadcare_file_group :attachments from the gem), and we do that 

uploadcare_document.attachments.load.files.each do |file|
  document = build_content_file(file)
  document = upload_file(document)
  delete_file_from_uploadcare(file)

  document.save!
  self.document = document
end

def build_content_file(file)
  uploadcare_uploaded_file = Uploadcare::FileApi.get_file(file.uuid)
  uploadcare_document.content_files.new(
    uploadcare_uploaded_file: uploadcare_uploaded_file,
    item_attributes: item_attributes(file)
  )
end

Expected behavior

There should be no errors
