An unexpected error occurs (e.g: NoMethodError undefined method `map' for nil:NilClass) When managing Ruby application's gem dependencies with bundler On Artifactory 6.7.0.

Description

An unexpected error occurs (e.g: NoMethodError undefined method `map' for nil:NilClass) When managing Ruby application's gem dependencies with bundler On Artifactory 6.7.0.

 

Steps to reproduce

$ bundle install --path ./test/bundle --verbose

If you need to re-run above command with change of Gemfile as following, you need to delete Gemfile.lock which will be created only in case gems are installed successfully.

1) When source indicate to gems-local

Gemfile

~~~~~~~ 

source 'https://rubygems.org/'

source 'http://127.0.0.1:8081/artifactory/api/gems/gems-local/'

gem 'sfn'

~~~~~~~~

==> this will works

Bundle complete! 1 Gemfile dependency, 39 gems now installed.

Bundled gems are installed into `./test/bundle`

You may need to delete Gemfile.lock at this time.

2) When source indicate to gems-remote

Gemfile

~~~~~~~ 

source 'https://rubygems.org/'

source 'http://127.0.0.1:8081/artifactory/api/gems/gems-remote/'

gem 'sfn'

~~~~~~~ 

 ==> This will fail due to remote repo of gems-remote as following errors.

Retrying dependency api due to error (2/4): NoMethodError undefined method `map' for nil:NilClass

Unfortunately, an unexpected error occurred, and Bundler cannot continue.

3) When source pointing to virtual repo such as gems

Gemfile

~~~~~~~ 

source 'https://rubygems.org/'

source 'http://127.0.0.1:8081/artifactory/api/gems/gems/'

gem 'sfn'

~~~~~~~

 ==> This will fail due to remote repo in side of gems virtual repository
