Hi Fehersanyi-Bitrise, here > **[Bitrise - Mobile Continuous Integration and Delivery](https://app.bitrise.io/users/sign_in)** > > Mobile Continuous Integration and Delivery for your whole team, with dozens of integrations for your favourite services. As far as logs are concerned, I think that the part involved is only the part I extracted earlier. ---

Since we do not use PackagerManager this time, we solved it by adding ‘- noUpm’ option. ---
