- Repository

- Base commit
- 2855b6b (image tag)
- Issue
- `alias` on `Optional` field breaks deserialization Hi there, Using the latest version (0.12.2), this example consistently deserializes `Foo.a` to `None`: ```py @serde @dataclass class Foo:
- Files to edit
serde/core.pyserde/de.py
- Approach
- Find where field aliases are resolved and ensure the alias `b` is used when deserializing `Foo.a` from `{"b": 1}`. Start by examining how aliases are handled in the serialization/deserialization process.

- Finish summary
- Fixed the issue where `alias` on `Optional` fields broke deserialization. The fix was in `serde/de.py` - the `opt` method now uses `_exists_by_aliases()` when the field has aliases, instead of using `conv_name()` which ignores aliases. This ensures that when deserializing `{"b": 1}` into a class with `a: Optional[int] = serde.field(alias=["b"])`, the field `a` correctly deserializes to `1` instead of `None`. All 2170 tests pass.
