You can't cache the jwk set with this example

[sombek]

I would suggest an update where you can cache jwk set

class JsonWebToken:
    """Perform JSON Web Token (JWT) validation using PyJWT"""

    jwt_access_token: str
    auth0_issuer_url: str = f"https://{settings.auth0_domain}/"
    auth0_audience: str = settings.auth0_audience
    algorithm: str = "RS256"
    jwks_uri: str = f"{auth0_issuer_url}.well-known/jwks.json"

    jwks_client = jwt.PyJWKClient( # having the client created once will keep the cache as long as the app running
        jwks_uri,
        ssl_context=ctx,
        cache_jwk_set=True,
        cache_keys=True,
    )

    def validate(self):
        try:
            jwt_signing_key = self.jwks_client.get_signing_key_from_jwt(
                token=self.jwt_access_token
            ).key
            payload = jwt.decode(
                self.jwt_access_token,
                jwt_signing_key,
                algorithms=self.algorithm,
                audience=self.auth0_audience,
                issuer=self.auth0_issuer_url,
            )
        except jwt.exceptions.PyJWKClientError as e:
            print(e)
            raise UnableCredentialsException
        except jwt.exceptions.InvalidTokenError:
            raise BadCredentialsException
        return payload
