#18784 __defaults__ does not support nested dicts Issue created by Ryan-Draves Describe the bug Using

__defaults__

to extend an

overrides

field is not supported; using

__defaults__(
    {
        (python_sources, ): dict(overrides={
            "*_generated.py": {
                "skip_yapf": True
            },
        })
    },
    extend=True,
    ignore_unknown_fields=True,
)

yields

TypeError: Even though you are using a `FrozenDict`, the underlying values are not hashable. Please use hashable (and preferably immutable) types for the underlying values, e.g. use tuples instead of lists and use FrozenOrderedSet instead of set().

Original error message: unhashable type: 'dict'

Value: FrozenDict({'overrides': {('*_generated.py',): {'skip_yapf': True}}})

while fudging the type of the

overrides

yields

InvalidFieldTypeException: The 'overrides' field in target my/path#__defaults__ must be dict[str | tuple[str, ...], dict[str, Any]], but was `(('*_generated.py',), (('skip_yapf', True),))` with type `tuple`.
