Bug Report

dvc pull: unexpected error

Description

I have several dvc resources imported into a project… The tracking files (.dvc) are committed to the repository utilizing these resources. When attempting to pull (dvc pull), the associated tracked resources - am getting an error:

An error occurred (400) when calling the HeadObject operation: Bad Request (relevant log from dvc pull —v below).

Reproduce

Example:

1. dvc import resource into project
2. latter or from a fresh checkout of the above git repo and then attempt to dvc pull

Expected

Expecting tracked resource to be retrieved from DVC. I am able to perform a dvc update <resource> and that will pull the dvc resource into the folder structure, of course this causes the .dvc file to show as modified (even though it points to the same location/revision).

How to proceed here? something corrupted?

Environment information

Output of dvc doctor:

$ dvc doctor
