Unclear error report: KeyError 'name'

[td-anne]

• Poetry version: Poetry (version 1.5.1)
• Python version: Python 3.8.10
• OS version and name: Ubuntu 20.04.6 LTS
• pyproject.toml: https://gist.github.com/td-anne/030e88ea2c564721d6d389fbebf3e16f

• I am on the latest stable Poetry version, installed using a recommended method.
• I have searched the issues of this repo and believe that this is not a duplicate.
• I have consulted the FAQ and blog for any relevant entries or release notes.
• If an exception occurs when executing a command, I executed it again in debug mode (-vvv option) and have included the output below.

Issue

When I try poetry commands I get a failure with unhelpful output:

$ poetry debug info

Poetry

'name'

If I use -vvv it seems this is a KeyError emanating from inside poetry:

$ poetry debug info -vvv

Poetry

This is probably because of something amiss in my pyproject.toml but the error message provides no indication of what.

pull requests welcome, I'm sure

@kevinzeidler that is completely different, please don't hijack this issue

[kevinzeidler]

You're right, my bad. Wasn't reading the stack traces carefully enough.

[GAC-BSP]

Same here! Not sure how to workaround the issue.

[TravisBumgarner]

Whelp getting this error too.

[TravisBumgarner]

Alright so what I gathered is

[project]
name = "gcode2dplotterart"
version = "0.0.1"
description = "Easily generate plotter art with your 2D Plotter or 3D Printer. This library abstracts away G-Code so you can focus on making art."
authors = [
  { name="Travis Bumgarner", email="[email protected]" },
]

[build-system]
requires = ["hatchling", "setuptools", "wheel"]
build-backend = "hatchling.build"

[tool.poetry.dependencies]
python = "^3.11.5"
mypy="^1.7.0"
black="^23.10.1"
flake8="^6.1.0"
pytest="^7.4.3"
matplotlib="^3.8.1"
numpy="^1.26.1"
setuptools = "^68.2.2"
wheel = "^0.41.3"
pydoc-markdown = "^4.8.2"

[project.urls]
"Homepage" = "https://github.com/TravisBumgarner/gcode2dplotterart"
"Bug Tracker" = "https://github.com/TravisBumgarner/gcode2dplotterart/issues"

This was my pyproject.toml.

I added the section

[tool.poetry]
name = "gcode2dplotterart"
authors = ["Travis Bumgarner"]
version = "0.0.1"
description = "Easily generate plotter art with your 2D Plotter or 3D Printer. This library abstracts away G-Code so you can focus on making art."

Which is really just a duplicate of the [project] section. But the error went away.
