Form file upload does not work

Hi guys!
I heve problem with attaching files to email message.
I have configured this fields:

form:
action: /contact
name: contact-form
fields:

......

-
name: my-file
label: 'Add a file'
type: file
multiple: false
destination: user/data/files
accept:

• application/pdf
• application/x-pdf
• image/png

• text/plain
  buttons:

  YAMLCopy

      type: submit
      value: 'Send Message'
      classes: 'btn btn-primary'
  

  process:

  TWIGCopy

      email:
          from: '{{ config.plugins.email.from }}'
          to: ['{{ config.plugins.email.to }}']
          subject: '[Contact] {{ form.value.name|e }}'
          body: '{% include ''forms/data.html.twig'' %}'
          content_type: 'text/html'
          charset: 'UTF-8'
          attachments:
          - my-file   
  

But still i receive messages without attachment.
Also ajax upload does not work and it looks like inactive button. I have to uncheck "display: none" in css properties.
Anybody have idea what is a problem?
