When a merge request decoration is attempted, I get the following error:

Here is my .gitlab-ci.yaml

ariables:
    SONAR_TOKEN: "<redacted>"
    SONAR_HOST_URL: "https://<redacted>"

analysis:sonarqube:
  stage: analysis
  tags:
    - docker
  allow_failure: true
  script:
    - bash ./gradlew sonarqube -Dsonar.qualitygate.wait=true
  only:
    - merge_requests
    - master
2

Nevermind, I had set the Gitlab CI URL to my Gitlab site URL (without the /api/v4 part) which is what caused the issue.
