Recursion error

Recursion error occurs when I try to write data to the database

tortoise config
DB_CONFIG = { 'connections': { # Dict format for connection 'default': { 'engine': 'tortoise.backends.asyncpg', 'credentials': { 'host': 'db', 'port': '5432', 'user': 'my_user', 'password': 'mysecretpassword', 'database': 'postgres', } }, }, 'apps': { 'models': { 'models': ["aerich.models", 'models.cargo', 'models.rate'], # If no default_connection specified, defaults to 'default' 'default_connection': 'default', } } }
tortoise connection in main.py
register_tortoise( app=app, config=DB_CONFIG, generate_schemas=True, add_exception_handlers=True )

tortoise model
class Cargo(models.Model): pk = fields.IntField(pk=True) name = fields.CharField(max_length=30)
pydantic model
class Cargo(BaseModel): pk: int name: str

endpoint
@router.post('/') async def post(cargo: pydantic.Cargo): return await Cargo.create(pk=cargo.pk, name=cargo.name)

Reproduce the endpoint using the shown Tortoise configuration and models, then inspect tortoise/models.py around lines 671, 698, and 775 where model initialization and primary-key assignment recurse. Done means the reported write no longer raises RecursionError and the Cargo record is created successfully.
