Error: Metadata API request failed: isomorphic-git error: Index file is empty (.git/index)

[vgoyal-copado]

Summary

We have a node script using which we are trying to kind of "take a snapshot" of the org. For this,

1. We create 8 child processes.
2. All these 8 child processes execute in parallel.
3. Each process retrieves at max 5000 members of a particular member type.
4. Each process uses the command sf project retrieve start --target-org <sessionId> --manifest <path-to-package-xml> --wait 60 --json to retrieve a particular member type.
5. If a process completes a retrieval, it goes on to pick the next metadata type and continues its retrieval

What we observe is: during the retrieval process, some retrievals fail with the error: Metadata API request failed: An internal error caused this command to fail. isomorphic-git error:Index file is empty (.git/index). As far as we have observed, this is happening only for sandboxes and not for regular developer edition orgs.

Steps To Reproduce

In an sfdx-repo ( the size of the repo doesn't matter, I have been trying this on an empty repo ), try to retrieve multiple metadatas in parallel from a sandbox.

Expected result

The metadata retrieval should be successful

Actual result

The metadata retrieval fails with the error: Metadata API request failed: An internal error caused this command to fail. isomorphic-git error:I ndex file is empty (.git/index)
