The requested URL was not found on the server (local server)

從 mergin/server/src/storages/disk.py 中的 move_to_tmp 開始，接著檢查 mergin/server/src/controllers/project_controller.py 中 push_finish 附近的程式碼。重現本機專案的 push，並沿著 traceback 追蹤 os.renames。完成標準是 push-finish 請求不再引發所回報的跨裝置連結錯誤，並回傳預期的回應。

During pushing new changes on the project, there is an error, when using server on localhost. So it have probably something with virtual environment.

Error: The requested URL was not found on the server. If you entered the URL manually please check your spelling and try again.
