If I remove the javascript_importmap_tags the errors stop appearing and it seems to be working fine, but I am not sure I should remove it as none of the documentation mentions it.

Any news? I want to add Vite to an application that already uses importmap and stimulus, do I have to remove importmap?

Having same issue on 7.1

This happens because when you include scripts from helpers like vite_javascript_tag (or really any module script using rails's javascript_include_tag helper), it will also preload those scripts by using early hints (setting the link header in the response).

When using importmaps, if you're also preloading a module script through the link header (or I'd assume even the link tag if you use it above the importmap definition) is not supported.

To "fix" (taking some perf hit), you can use the option preload_links_header: false when including module scripts, introduced here:

<%=  vite_client_tag(preload_links_header: false) %>
<%=  vite_javascript_tag('application', media: 'all', data: { turbolinks_track: true, turbo_track: 'reload' }, preload_links_header: false) %>

Background

I am using Ruby on Rails version 7.2 gem 'rails', '~> 7.2.0' and jsbundling-rails gem 'jsbundling-rails', '~> 1.3', '>= 1.3.1' with esbuild
and Vite Ruby (gem 'vite_rails', '~> 3.0', '>= 3.0.17') and importmaps gem 'importmap-rails', '~> 2.0', '>= 2.0.3'

I keep seeing error messages in Chrome Console

An import map is added after module script load was triggered.
Uncaught TypeError: Failed to resolve module specifier "application". Relative references must start with either "/", "./", or "../".

This solves the problem

# config/environments/development.rb

Rails.application.configure do
  # Disable `Link: ... rel=preload` header to workaround Safari caching bug
  # https://bugs.webkit.org/show_bug.cgi?id=193533
  config.action_view.preload_links_header = false
end
