Issue Summary

Bitbucket Cloud currently does not support Git repositories initialized with the SHA-256 object format (--object-format=sha256). As SHA-256 provides enhanced security and has been officially supported by Git since version 2.29, it would be beneficial for Bitbucket Cloud to support repositories using SHA-256. This would enable organizations and developers to adopt the more secure hashing algorithm while continuing to use Bitbucket Cloud for hosting and collaboration.

Steps to Reproduce

1. Initialize a Git repository with SHA-256:

   git init --object-format=sha256

1. Attempt to push the repository to a Bitbucket Cloud repository:

   git remote add origin https://<username>@bitbucket.org/<workspace>/<repo>.git
   git push -u origin main

Expected Results

Bitbucket Cloud should support repositories using SHA-256, allowing users to push, pull, and perform all Git operations seamlessly.

Actual Results

Currently, Bitbucket Cloud does not support SHA-256 repositories. When attempting to push, users encounter an error

fatal: the receiving end does not support this repository's hash algorithm
fatal: the remote end hung up unexpectedly
