RuntimeError: An attempt to run a request with a Faraday::Connection without adapter has been made

[oleksii-mykhniak]

I'm using dpl in GitLab for Heroku CI/CD and I have the next error:

/usr/local/bundle/gems/faraday-2.0.0/lib/faraday/rack_builder.rb:230:in `ensure_adapter!': An attempt to run a request with a Faraday::Connection without adapter has been made. (RuntimeError)
Please set Faraday.default_adapter or provide one when initializing the connection.

It looks like a problem in the faraday-2.0.0 release which was a few minutes ago here

Here is a quick and dirty workaround.

Add gem install faraday -v 1.8.0 before running dpl --provider=heroku --app=$APP --api-key=$HEROKU_API_KEY.

It ain't pretty, but DEV's got to deploy.

It looks like the change affected was lostisland/faraday#1354

[maidh91]

This is my update for Gitlab CI, works perfectly with Faraday 1.8.0

deploy:
  stage: deploy
  only:
    - master
  image: ruby:latest
  script:
    - gem install dpl && gem install faraday -v 1.8.0
    - dpl --provider=heroku --app=xxx --api-key=$HEROKU_API_KEY

lostisland/faraday#1362 (comment) says that Faraday 2.0.1 reverted/fixed the change that made Faraday 2.0.0 not work but I put up #1249 just in case that doesn't work or it changes, so that someone who is maintaining dpl can qualify dpl against Faraday 2.x properly.

I faced the same problem today. Apparently there is some problem in the latest version of FARADAY, at the moment. I solved it this way: add manual installation of the previous version of the dependency to your .gitlab.yml, and everything will work. Have a nice day.

before_script:
  - apt-get update -qy
  - apt-get install -y ruby-dev
  - gem install dpl
  - gem install faraday -v 1.8.0
