ERROR: Error during SonarScanner execution You're not authorized to run analysis. Please contact the project administrator

Hi @acki , welcome to the community forum.

Thanks for the links to the PR!
I see you are trying to analyze the PR from a fork. This feature is currently not supported for CI-based analysis, only for automatic analysis.
It’s already identified on our side, but not planned (some links to follow the progress are on this other thread). You can also vote on that issue: SonarCloud analyzes external Pull Request - SonarCloud | Product Roadmap
