Local 'oid' is nil value during many Neogit actions

Description

Whenever I do any of a number of actions in Neogit, I get this error, sometimes twice:

vim.schedule callback: [neogit async] ...ocal/nvim-data/lazy/neogit/lua/neogit/lib/git/bisect.lua:89: attempt to index local 'oid' (a nil value)
stack traceback:
        ...ocal/nvim-data/lazy/neogit/lua/neogit/lib/git/bisect.lua: in function 'fn'
        .../nvim-data/lazy/neogit/lua/neogit/lib/git/repository.lua:254: in function <.../nvim-data/lazy/neogit/lua/neogit/lib/git/repository.lua:252>
stack traceback:
        [C]: in function 'error'
        ...ata/Local/nvim-data/lazy/neogit/lua/neogit/lib/async.lua:277: in function <...ata/Local/nvim-data/lazy/neogit/lua/neogit/lib/async.lua:276>

This happens whenever I run a command in Neogit (like x to discard), open Neogit with the :Neogit command, or unfocus and refocus the Neovim window.

Neovim version

NVIM v0.12.2
Build type: Release
LuaJIT 2.1.1774638290

Operating system and version

Windows 11

Steps to reproduce

1. nvim -u minimal.lua
2. :Neogit (Error appears on launch)
3. Run any command inside neogit (Error appears)

Expected behavior

Doing an action in Neogit performs that action as intended without the pop error.

Actual behavior

The action still gets done, but a popup shows up once or twice in a row with the above error before the action is performed.

Start by reading lua/neogit/lib/git/bisect.lua at line 89 and the callback path in lua/neogit/lib/git/repository.lua around line 252. Use the supplied minimal.lua reproduction, then launch :Neogit and run an action to confirm the nil-value popup no longer appears.
