Hello @Daniel_Barreto_dos_S ,

Note: There is no manual billing sync process at our end.

This issue occurs because the Cloud Billing account 012A94-AA5834-B6... linked to project gen-lang-client-086446... is currently closed or not in good standing.

Next steps:

  • Check your billing account status in Google Cloud Console and resolve any account holds or reopen the closed billing account.
  • Alternatively, link your project to another active Cloud Billing account in good standing.
  • If you still face issues post the above steps, let us know.
