Aurelia - DevTools failed to parse SourceMap

Since upgrading to Chrome 71, my team has experience an issue with Chrome not being able to parse our SourceMaps. I'm currently on Version 71.0.3578.98 (Official Build) (64-bit).
The 3 failing maps are:
vendor-bundle.js.map
app-bundle.js.map
bootstrap.css.map
Details:
ASP.NET Core 2.1
It is an Aurelia app using Babel compiler
Sourcemaps are turned on for "dev & stage"
"sourceMap" is set to true in .babelrc
using gulp-sourcemaps
"gulp-sourcemaps": "^2.6.4"
We are quite sure that the only variable that changed was upgrading from Chrome version 70 to 71 because we tried the same code in each version of the browser. Since we have restarted Chrome and it has auto-updated, we all have noticed that source maps fail once upgraded to version 71.
I have been following this seemingly related thread on GitHub

Thank you in advance for any assistance.

upgrade fipl/whoops 2.* in laravel 4.2.*

I using laravel 4.2.19 with php7 then have problem with Exception, I search and see problem in php7 remove Exception class and fipl/whoops 1.* then not working but upgrade to version 2.* then will working with php7.
images error when require fipl/whoops 2.*
And my problem how to upgrade fipl/whoops 1.* to 2.* in laravel 4.2.19 ?
The image you shared shows that Laravel 4.2.x doesn't support the package version you are going to install.
The better is to upgrade from 4.2 to minimum 5.1 to use PHP7 without issues.

Where are the JRuby native headers installed when installing with RVM?

I am using OS X 10.8, and I installed JRuby using RVM (rvm install jruby). I can see JRuby-1.7.6 is installed at ~/.rvm/rubies/jruby-1.7.6, but I don't see ~/.rvm/rubies/jruby-1.7.6/lib/native/include/ruby/ directory there. Later when I tried to build a native extension (jruby -S gem install posix-spawn), I got an error message saying that
~/.rvm/rubies/jruby-1.7.6/lib/ruby/shared/mkmf.rb:14: Use RbConfig instead of obsolete and deprecated Config.
mkmf.rb can't find header files for ruby at ~/.rvm/rubies/jruby-1.7.6/lib/native/include/ruby/ruby.h.
How can I fix this issue?
posix-spawn is only compatible with MRI Ruby, it could work with Rubinius but will not work with JRuby because it does not support C Extensions.

Problem with installing rails-3 plugins (Win7)

I'm newbie at ruby, I spent couple hours trying to find the way to install the plugin... but without any success, so here I am, very frustrated... please help.
OS: W7
ruby: ruby 1.9.2
rails: 3.0.5
msysgit: 1.7.4 (i did not any changes, just installation)
(is there anything else I should of mentioned?)
ruby script/plugin install git://github.com/thoughtbot/paperclip.git/
C:\Ruby\Ruby192\bin\ruby.exe: Permission denied -- script/plugin (LoadError)
Thank you!
The script/plugin command (and all other script/<exec> commands) is no longer used in Rails 3, instead you should do:
rails plugin install git://github.com/thoughtbot/paperclip.git
