tool.ruff throwing invalid type: sequence, expected a map

[c-kiran]

Hello,

I am new to RUFF and I am trying to use RUFF on my code base to improve readability. I am updating my pyproject.toml in support of RUFF from flake8, pylint, isort (I am aware not all rules from flake8, pylint, isort) are fully implemented in RUFF but the error doesn't have anything to do with those implementations.
My pyproject.toml looks like below

[tool.ruff]
line-length = 120
target-version = "py310"

# Enable Pylint and other relevant rules
select = [
    "E", "F", "W",          # pycodestyle, pyflakes, warnings
    "C90",                  # mccabe (complexity)
    "PL",                   # pylint plugin
    "I",                    # isort
]
ignore = [
    "PLR0913",  # Too many arguments
    "PLR0914",  # Too many local variables
    "PLR0912",  # Too many branches
    "PLR0904",  # Too many public methods
    "PLR0915",  # Too many statements
    "PLR0911",  # Too many return statements
    "PLW0603",  # Global statement
    "PLR1702",  # Too many nested blocks (bool expressions)
    "PLR0917",  # Too many positional arguments
]

[tool.ruff.lint.mccabe]
max-complexity = 25  # similar to `max-branches`

[tool.ruff.isort]
combine-as-imports = true
force-sort-within-sections = true
sections = ["future", "standard-library", "third-party", "second-party", "first-party", "data", "local-folder"]
known-data = ["data"]
known-local-folder = ["config"]

Any help in fixxing error in TOML files, I am not sure why I am getting error.

I have Ruff Language Server selected in VS Code terminal OUTPUT tab in case if it supposed to be #15991, where I don't see ruff server instead only Ruff

I think the TOML parsing issue is from your tool.ruff.isort.sections setting. There's not actually a complete example in the documentation, but I think it needs to be a TOML map like this:

sections = { "future" = [], "standard-library" = [], "third-party" = [], "second-party" = [], "first-party" = [], "data" = [], "local-folder" = [] }

where you include the packages you want to add to the section in the nested lists.

This is probably a better way to format it:

[tool.ruff.isort.sections]
future = []
standard-library = []
third-party = []
second-party = []
first-party = []
data = []
local-folder = []

Alternatively, I think your input might be valid for the section-order option, so you could also just replace sections with section-order if that's what you meant.
