Display field in views-view-field--field_title.html.twig If I have view with fields:

field title [hidden]
field text [hidden]
field image [hidden]
field display


and I make rewrite in "display" field with "title" and "text" field added, how can I print content of field "image" (url of this image) with views-view-field--field_display.html.twig? I need wrapper with image url from this field. I see all available variables (view, field, row, output) in template and suggestion to fetch output with construct: 

data = row[field.field_alias]


but when I try to write twig code with my field_image alias it's not showing me anything. Field with image is set up to display just url to image. I translated few code lines from drupal 7 to twig, but I am unable to see anything in kint, just dump show me some key strings. Views create block and I am placing this block on my page.

What I am doing wrong?
URL FORMATTER module

This module add a url formatter for image field. Then you can output image url directly.

Enable the module, then in views, click on your image field, and change the Formatter to Image url.
{{ field_with_image_url }}  // will display url instead of picture
