In package.json the private package is imported as:

"@coinsamba/exchange-common": "ssh://"

I already added the netlify public key in the repository and the error still persists.

hi there, could you paste the full build log please? thanks.

done, and put it as I added the private package

no, can you link us to or paste the full build log here, please, as opposed to the abbreviated version above. thanks.

all the log is already in the thread

:wave: @itxtoledo ,

I suggest the following Support Guide should offer some guidance in this instance:

Let us know if that helps.

It is unfeasible to commit these keys as they give access to several other repositories in my account for other people who have access to this repository.

This unsolved problem made me leave for a competitor, thank you.
