Artifacts are no longer being generated

My problem:

My circle.yml file is set up to upload the protractor report, but lately I’m getting the message: _We didn’t find any build artifacts for this build. You can upload build artifacts by moving files to the $CIRCLE_ARTIFACTS directory.

My tests are passing normally, the only problem is when it comes to generating the artifact. It’s strange because in other projects I use exactly the same configuration of circle.yml and the report is generated normally

My stack:

I’m using Protractor and to generate reports I’m using protractor-jasmine2-html-reporter

My circle.yml:

general:
  artifacts:
    - "test_evidences"
general:
  branches:
    only:
      - development

machine:
  node:
    version: 6.10.3

dependencies:
  pre:
    - curl -L -o google-chrome.deb https://dl.google.com/linux/direct/google-chrome-stable_current_amd64.deb
    - sudo dpkg -i google-chrome.deb
    - sudo sed -i 's|HERE/chrome\"|HERE/chrome\" --disable-setuid-sandbox|g' /opt/google/chrome/google-chrome
    - rm google-chrome.deb
    - npm install
  override:
    - node_modules/.bin/webdriver-manager update

test:
  override:
    - node_modules/.bin/protractor conf.js
    - sed -i -- 's,//,/,g' test_evidences/htmlReport.html

How can I fix this?
