Answer 1

You configured VCS root in the Teamcity, so before the build starts, Teamcity will automatically checkout required repository paths to the local machine.

The problem you showed in the original log is different: npm is trying to connect to bitbucket repository to install some dependencies and fails, because authorization.

To solve this issue, you have to configure SSH key for Teamcity user (user as far as I can see from your log). You can verify that it works via running the same command from the original host, where Teamcity agent sits:

git clone 'https://git@bitbucket.org/team/repo.git/'

Otherwise, you have to change the source of your dependencies: maybe you have an Artifactory instance somewhere, which doesn't require authorisation.
