Invalid option "--api_key="

Hello,

I have a strange situation with deployment
https://travis-ci.org/aspel/twitchview-go/builds/604886542
Here is my code

deploy:
  provider: releases
  api_key: $GITHUB_TOKEN
  file:
    - "${TRAVIS_BUILD_DIR}/twitchview-go.darwin.tar.xz"
    - "${TRAVIS_BUILD_DIR}/twitchview-go.linux.tar.xz"
    - "${TRAVIS_BUILD_DIR}/twitchview-go.win.tar.xz"
  skip_cleanup: true
  on:
    tags: true

Travis return this error, but deployment was success.
All tar files ware uploaded to GitHub.

$ rvm $(travis_internal_ruby) --fuzzy do ruby -S gem install dpl
Fetching: dpl-1.10.13.gem (100%)
Successfully installed dpl-1.10.13
gem installed

Found the problem. There are 2 sites travis/com travis/org.
Some how my pipeline was deployed on both sites. One of them was success.
