I am writing a smart contract with seahorse. However it successfully build and deployed, but when I run the addProduct() test, it fails It is giving me the error-

Testing 'addProduct'...
❌  Test 'addProduct' failed: 
Instruction index: 0
Reason: Program failed to complete.

Here is my smart contract -

# Built with Seahorse v0.2.4

from seahorse.prelude import *

declare_id('A81QxcQJrfZprjbNkvC9a9gSi2huQu45bSDsECTX2aJE')

class UserProfile(Account):
  owner: Pubkey
  name: str
  email_address: str
  phone: str
  address: str
  role: str #Supplier or Buyer
  no_of_products: u64

class Product(Account):
  # Relation with Supplier
  owner: Pubkey
  product_id: u64
  name: str
  description: str
  price: f64
  quantity: u64
  image_url: str

class Transaction(Account):
  product_id: u64
  product_owner: Pubkey
  buyer: Pubkey
  amount: f64
  created_at: str
  transaction_type: str #Ordered or Delivered

@instruction
def create_user(

  user: Empty[UserProfile],

  user_profile = user.init(
    payer = owner,
    seeds = ['user', owner],
  )
  user_profile.owner = owner.key()
  user_profile.name = name
  user_profile.email_address = email_address
  user_profile.phone = phone
  user_profile.address = address
  user_profile.role = role
  user_profile.no_of_products = 0

@instruction
def add_product(

  price: f64,
  quantity: u64,
  image_url: str,
):
  assert user.owner == owner.key(), 'Incorrect Owner'
  assert product_id == user.no_of_products + 1, 'Incorrect Product ID'

  product_account = product.init(
    payer = owner,
    seeds = ['product', owner, product_id],
    # space = 8 + space
  )
  product_account.owner = owner.key()
  product_account.product_id = product_id
  product_account.name = name
  product_account.description = description
  product_account.price = price
  product_account.quantity = quantity
  product_account.image_url = image_url

  user.no_of_products += 1

  new_product_event = NewProductEvent(product_account.owner, product_account.product_id)
  new_product_event.emit()

### Events ###

class NewProductEvent(Event):
  owner: Pubkey
  product_id: u64

  def __init__(self, owner: Pubkey, product_id: u64):
    self.owner = owner
    self.product_id = product_id

Could you please help me out with the error. I am new to the Solana + Seahorse Ecosystem.

Thank You
