Unable to handle TOML with mixed-value arrays (as used by dependency groups) #25413
Description
Type: Bug
Behaviour
The extension is unable to parse TOML files which have lists containing a mixture of types.
This is an issue when using Dependency groups such as:
[dependency-groups]
dev = [
"ruff==0.12.9",
{ include-group = "test" },
]
test = ["pytest"]Steps to reproduce:
- Add the above section to a project using
pyproject.toml, and watch the logs.
Additional Details
The error originates from the isPipInstallableToml function and is in fact an error within the upstream @iarna/toml package. See the upstream bug report.
