[Python] FastAPI throws 422 error when trying to add a File Upload [duplicate]

I want to have a call that takes in both a json form for a 'product' and a image file to save along with it. I've tried doing so with this code

@app.post("/products")
def create_product(product: Product, file:UploadFile = File(...), db: Session = Depends(get_db)):

product_model = models.Products()
product_model.name = product.product_name
product_model.description = product.description
product_model.remaining_quantity = product.start_quantity
product_model.start_quantity = product.start_quantity
product_model.limit_per_user = product.limit

product_model.is_featured = product.is_featured
product_model.is_open = product.is_open



db.add(product_model)
db.commit()

return product


Before I added the functionality of saving the image, I realized the call wouldn't work anymore and I keep getting a

{
"detail": [
{
"loc": [
"body",
"product"
],
"msg": "value is not a valid dict",
"type": "type_error.dict"
}
]
}


I don't know why this is the case.

I've tried separating the image upload to another class, and that actually worked, but I want them to be all in one call. Is there something wrong with how I'm writing my method header?
