We have the same issue since yesterday on our SonarCloud. This breaks our build pipeline, since we’re checking if there any error messages in the log, which is required to ensure that CLI analyzer actually was run, since when it can’t run build won’t fail otherwise (see How to fail pipeline when SonarCloudAnalyze has an error on Azure DevOps - #14 by gab).
As long as there is no way to ensure that CLI analyzer was successfully run, nevertheless what the reason was why it was not able to run, this is a breaking issue.
