AttributeError: 'MemoryObjectStore' object has no attribute 'add_pack_data'

Hi,

I just updated from 0.20.50 to 0.21.3 and I'm getting this error now:

Traceback (most recent call last):
  #
  # START my code
  #
  File "/Users/xyz/Projects/fs-code/src/codefs/_core.py", line 108, in _delegate

    target.object_store.add_pack_data(count, pack_data, progress)
  #
  # END dulwich
  #
AttributeError: 'MemoryObjectStore' object has no attribute 'add_pack_data'

This is how I'm initializing the repo:

# tmp_path is a Path fixture from pytest
porcelain.init(repo := str(tmp_path))
(test_file := tmp_path / "file").write_text("something")
porcelain.add(repo, str(test_file))
porcelain.commit(repo, message="test")

Is this a bug?
