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

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.

On the server itself i get this error:

mergin/server/src/storages/disk.py の move_to_tmp から始め、次に mergin/server/src/controllers/project_controller.py の push_finish 付近を調べます。ローカルプロジェクトの push を再現し、os.renames を通る traceback を追跡します。push-finish リクエストで報告されているクロスデバイスリンクエラーが発生しなくなり、期待されるレスポンスが返されれば完了です。
