Minimal Reproduction for Renovate failing to parse valid TOML v1.0.0 spec.

This reproduction demonstrates how renovate fails to parse a valid pyproject.toml.

You can see the parsing error via the action logs here.

See renovatebot/renovate#18668 for more details.

The Bug

The exact error is as follows:

DEBUG: Found asdf package files (repository=bradenm/renovate-toml-v1-repro)

It is caused by the following excerpt from pyproject.toml:

renovate-toml-v1-repro/pyproject.toml

Lines 8 to 11 in ae92c26

	include = [
	"README.md",
	{ path = "tests", format = "sdist" }
	]

The problematic toml lines are valid according to the latest TOML spec:

Array

Arrays are square brackets with values inside. Whitespace is ignored. Elements are separated by commas. Arrays can contain values of the same data types as allowed in key/value pairs. Values of different types may be mixed.

Info

This repo has a simple workflow that:

• Uses poetry to validate the pyproject.toml
• Executes the latest renovate/renovate docker image to reproduce the failure
