Unable to parse the pyproject.toml file.

here is the exception stack:

TypeError: Array.__init__() missing 1 required positional argument: 'trivia'

I typed the command: tbump current-version
This is my pyproject.toml:

[tool.tbump]
field = [
    { name = "channel", default = "" },
    { name = "release", default = "" },
]
file = [
    { src = "pyproject.toml", version_template = "version = \"{major}.{minor}.{patch}{channel}{release}\"" },
    { src = "ipywebcam/_version.py" },
]

I have debug the command, And found the problem.
return type(data)(o.validate(d, **kwargs) for d in data)
This line cause the exception. It's in schema.py line 366.
I found data here is not a native python list, but tomlkit.items.Array.

class Array(Item, _CustomList):
    """
    An array literal
    """

    def __init__(self, value: list, trivia: Trivia, multiline: bool = False) -> None:
        super().__init__(trivia)
        ...

You can see to construct a Array instance, you must provide a trivia as argument.

But why data is not a list? I found when you call ConfigFile.get_parsed, it return a value with toml special type instance, which caused the issue.

So I think to fix this issue, the config returned by ConfigFile.get_parsed should be clean to a pure python instance with list and dict.

Here is a quick fix:

class PyprojectConfig(ConfigFile):
    """Represent a config inside a pyproject.toml file,
    under the [tool.tbump] key
    """

    def __init__(self, path: Path, doc: TOMLDocument):
        super().__init__(path, doc)

    def get_parsed(self) -> dict:
        try:
            # tool_section = self.doc["tool"]["tbump"].value
            # use unwrap here. then we will get a plain python object
            tool_section = self.doc.unwrap()["tool"]["tbump"]
        except KeyError as e:
            raise InvalidConfig(parse_error=e)

        return tool_section.value  # type: ignore

I'm seeing the same issue.

@dmerejkowsky When will the new version be released? Even though pr was merged, it was still the old version on pip for months

[dmerejkowsky]

tbump 6.10.0 has been released and contains this fix. Enjoy :)
