When doing bender config, an error shows up:

error: Dependency `lib-xxx` from ``https://<internal_address>/lib-xxx`` cannot satisfy requirement `^0.1.0`, may need fetch.

When pulling the repo normally with --branch 0.1.0, there are no issues, confirming that the tag exists. I can't seem to find information about this issue.
What has gone wrong here, and is there a fix?
