Okay, guys I finally solved the issue. Actually, it was more than one reason that caused it.

First I replaced this line:

<%= form_with(url: export_path, method: 'get', local: true) do |f| %>

with this line:

<%= form_with(url: export_path(format: "csv") , method: 'get', local: true) do |f| %>

thanks to my friend Jamie Crone

replace this line

<%= form_with(url: export_path, method: 'get', local: true) do |f| %>

with...

<%= form_with(url: export_path, method: 'get', local: true, format: :csv) do |f| %>

does anything download if you put this in the browser http://localhost:3000/export_path.pdf

Try changing this

<%= form_with(url: export_path, method: 'get', local: true) do |f| %>

with this

<%= form_with(url: export_path(format: "csv") , method: 'get', local: true) do |f| %>
