Hi @jareko999, you (or a gem you depend on) have just updated Faraday to v2.0.
This being a major version, it comes with some backwards incompatible changes, including the one causing the error you see.
Please refer to the UPGRADING.md file for instructions on how to upgrade, or simply fix the Faraday version to < 2.0 in your Gemfile.

#1360 see here for a workaround for that specific gem.

I'm leaving this open for the time being as I'd expect more people falling into this. Marked it with info label

[jareko999]

Thanks. Looks like dpl was the culprit.

This workaround worked for me: travis-ci/dpl#1247 (comment).

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

I'm closing this because Faraday 2.0.1 has now re-introduced net_http as both a dependency and the default adapter, so there's no need for workarounds anymore 🎉
