• I am sure the error is coming from Pyrofork's code and not elsewhere

Description

Pyrofork version: 2.3.68, 2.3.69
Python version: 3.11
Operating System: Linux

When calling client.send_gift() with the text parameter, the method raises a TypeError because entities is None instead of an empty list []

The gift should be sent successfully with the text message attached, but the method raises the following error:

TypeError: object of type 'NoneType' has no len()

Traceback:
File "pyrogram/methods/payments/send_gift.py", line 90, in send_gift
form = await self.invoke(
File "pyrogram/raw/types/text_with_entities.py", line 79, in write
b.write(Vector(self.entities))
File "pyrogram/raw/core/primitives/vector.py", line 74, in new
[Int(cls.ID, False), Int(len(value))]
TypeError: object of type 'NoneType' has no len()

In pyrogram/methods/payments/send_gift.py line 87:
message=raw.types.TextWithEntities(text=text, entities=entities) if text else None

When text is provided but entities is None (default), the TextWithEntities object is created with entities=None. Later, when Pyrogram tries to serialize this object, it calls len(self.entities) which fails because None has no length.
I tried change line 87 to:
message=raw.types.TextWithEntities(text=text, entities=entities or []) if text else None

Steps to reproduce

from pyrogram import Client

app = Client("my_account")

async with app:
# This will fail with TypeError
await app.send_gift(
chat_id=123456789,
gift_id=5170233102089322756,
text="Hello! This is a gift message"
)

Code example

if message_text and message_text.strip():
                    await client.send_gift(
                        chat_id=user['user_id'],
                        gift_id=5170233102089322756,
                        text=message_text.strip()
                    )
                else:
                    await client.send_gift(
                        chat_id=user['user_id'],
                        gift_id=5170233102089322756
                    )
