Hello there!

Could you pease send us the url of the latest build please? so we can check the logs for additional information?

Hi Fehersanyi-Bitrise,


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.


Hy @lynmock!

I’m glad you could solve it, and thanks for sharing the fix as well.

Hi @lynmock,

Thanks for sharing your issue and the solution as well. I shall close this topic, but feel free to open a new one, should there be anything else you need help in! :slight_smile:
