Reading application.scss under the node_modules directory?

[ruedap]

I have a problem with Sass::SyntaxError in LetterOpenerWeb::Letters#index occurs.

Environment

• ruby 2.5.0p0
• rails 5.2.0
• letter_opener_web 1.3.4

Steps to reproduce the problem

# With letter_opener_web working properly

$ mkdir -p node_modules/foobar
$ touch node_modules/foobar/application.scss
$ echo ".foo { top: \$bar; }" > node_modules/foobar/application.scss
$ open http://localhost:3000/letter_opener

# An error occurs

Error

Is this a bug?
Why are you reading application.scss under the node_modules directory?

Thanks 😃

I was wrong. This behavior seems to be the default from Rails 5.1. 😇
