Bug: OpenAPI schema error when using pydantic.SecretStr with a pydantic.Field

[byte-bot-app]

Reported by seels in Discord: <#1212255742954971207>:

Hey, all. I'm getting the following error when using a SecretStr attribute (from Pydantic) and accessing /schema/openapi.json: type object 'SecretStr' has no attribute 'item_type'. I've got SecretStr: str in my type_encoders, but that doesn't seem to help.

MCVE:

from litestar import post
from pydantic import BaseModel, Field, SecretStr


class Something(BaseModel):
    password: SecretStr = Field(min_length=8)


@post()
async def something(data: Something) -> Something:
    return data


from litestar.testing import create_test_client

with create_test_client([something]) as client:
    print(client.get('schema/openapi.json').json())

This only happens when password is set to a Field. It works fine when it's just password: SecretStr.
