PR scan results not showing on SonarCloud

SonarQube Cloud
1

Context

  • ALM: GitHub (private repo)
  • CI: GitHub Actions, SonarSource/sonarqube-scan-action@v8 (SonarScanner CLI 8.1.0.6389)
  • Plan: Free, private project, CI-based analysis (Automatic Analysis disabled)
  • Languages: Java 21 (Maven), TypeScript (Angular)

Problem
Since Sept 24, 2026, pull request analyses complete successfully but the pull requests
never show up in the project:

  • The two PRs analyzed on Sept 24 are missing from Project > Pull Requests.
  • Opening summary/new_code?id=<project>&pullRequest=<n> for these PRs renders a blank page.
  • The issues link in the PR decoration comment silently falls back to the main branch,
    so main branch issues are shown instead of the PR ones.

What works

  • The scanner auto-detects the PR (Pull request N for merge into main from <branch>),
    resolves the merge base and reports QUALITY GATE STATUS: PASSED.
  • GitHub PR decoration (check + comment) is posted.
  • All related background tasks end in SUCCESS.
  • api/ce/task?id=<task> returns status SUCCESS with the expected pullRequest value,
    and warningCount: 1 with an empty warnings array.
    Warning shown in Background Tasks UI:

What changed
Nothing on our side: no change to the workflow or sonar-project.properties since the last
PRs that are correctly listed (Sept 23). The main branch analysis of Sept 24 also succeeded.

Question
Can you check why these successful PR analyses are not attached to / listed in the project,
and whether the hidden task warning is related? I can share the organization, project key,
task IDs and analysis ID in a private message.
