Unable to pdm sync / install an application with uv without a project name / version

[taborsarah]

Describe the bug

When uv is enabled, I am unable to pdm sync or install an applicaction without a project name and version.

To reproduce

Create a new project with a pyproject.toml file w/ no project name or version.

[project]
description = "A demonstration."
authors = [
    {name = "Sarah Tabor", email = "[email protected]"},
]
dependencies = [
    "pandas>=2.2.3"
]
requires-python = ">=3.11,<3.13"
license = {text = "MIT"}

[[tool.pdm.source]]
url = "https://gitlab.beta.team/api/v4/projects/beta%2Fpypi/packages/pypi/simple"
verify_ssl = true
name = "pypi"

Ensure uv is enabled for the project. pdm config use_uv true

Try to pdm install

Expected Behavior

I should be able to use pdm for an application with uv enabled
