Error : Web push send from python backend to fire base using VAPI keys. Unhashable type:'slice' about pywebpush HOT 7 OPEN

@ishwara-bhat I have the same problem, how could you solve it?

from pywebpush.

Reading the dump, it appears that the problem is that http_ece can't encrypt content.
content comes from data in self.encode(data, content_encoding)

from a very quick view, I'm going to guess that the data being passed in is not a byte array. You may need to serialize the object content into a string or byte array before passing it to webpush.encode

An example of a key pair that I am using are the following. I am using string strings directly.

{
"subject": "mailto: [email protected]",
"publicKey": "BLR4PgElXtaeu16JlFEfVuOZkyub-Y36w1XRDYvl7-gNOKUpW-YadhR0Yv6vnrz5h4HhJG5jq0arBRuIrJdWXtQ",
"privateKey": "LqUduWL7V0F7pOrYep5oTgZJaCXLl7eRvMZMpAE6DCA"
}

Is it necessary to use PEM certificates or can I use string keys?

String keys can be in either raw or DER format: https://github.com/web-push-libs/vapid/blob/main/python/py_vapid/__init__.py#L134-L147. If you provide a path, py_vapid will try to read the file as either PEM or DER formatted https://github.com/web-push-libs/vapid/blob/main/python/py_vapid/__init__.py#L134-L147

Las claves de cadena pueden estar en formato raw o DER: https://github.com/web-push-libs/vapid/blob/main/python/py_vapid/__init__.py#L134-L147 . Si proporciona una ruta, py_vapid intentará leer el archivo con formato PEM o DER https://github.com/web-push-libs/vapid/blob/main/python/py_vapid/__init__.py#L134-L147

Ok, I will try to work with the private key in PEM format from the file directly.

Just ran into this same issue. Make sure your data payload is JSON string encoded and not just a raw python dictionary.
