Azure : SonarQubePublish@4 : Unrecoverable indexation failures

Hi Sonar,

We recently started to use SonarQube Azure build pipeline extension, community edition.
It did work a few times, but now all the builds display this error:

Starting: Publish Quality Gate Results
Task         : Publish Quality Gate Result
Description  : Publish SonarQube's Quality Gate result on the Azure DevOps build result, to be used after the actual analysis.
Version      : 4.8.1
Author       : sonarsource
Help         : [More Information](
##[error][SQ] Task failed with status FAILED, Error message: Unrecoverable indexation failures: 1 errors among 1 requests
Finishing: Publish Quality Gate Results

Here is the yaml we use for the step:

  - task: SonarQubePublish@4
      pollingTimeoutSec: '300'
    displayName: 'Publish Quality Gate Results'

The build runs on Azure-hosted agents, Win 2019.
Is there anything you can recommend for troubleshooting?
