decimal.InvalidOperation in Tortoise ORM

Here's how my model is defined:

class User(Model):
    id = BigIntField(primary_key=True, source_field="user_id")
    text = CharField(max_length=255, null=True)
    decimal = DecimalField(max_digits=27, decimal_places=27)

Let's consider this example where I create a user and pass him a random decimal number:

async def test():
    user = await User.create(decimal=1234567890.3)
    ...

This throws this error:

decimal.InvalidOperation: [<class 'decimal.InvalidOperation'>]

I suppose Tortoise ORM uses Decimal library under the hood to manage this field. I know nothing about this library. Tortoise ORM docs state that I just need to specify the number of decimal places and max digits for it to work. Can someone explain what am I doing wrong?
