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

Start in mergin/server/src/storages/disk.py at move_to_tmp, then inspect mergin/server/src/controllers/project_controller.py around push_finish. Reproduce the local project push and follow the traceback through os.renames. Done means the push-finish request no longer raises the reported cross-device link error and returns the expected response.

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.
