Private update to specific users = not authorized

[cvergne]

Hi,

I was trying to implements private updates with alternate topics as mentioned in the documentation, but without success.
So I tried exactly what is in the documentation (to check if it was from my code), but I can't make it work.

I'm trying to do the "Subscribers" part of the "Authorization" documentation ( https://mercure.rocks/spec#authorization )

When I do, with mercure in debug mode, I receive no update and in logs I have the following statement :

(Note I'm using current last version of mercure: v0.11.2)

{
    "level": "debug",
    "ts": 1619447991.06735,
    "logger": "http.handlers.mercure",
    "msg": "Subscriber not authorized to receive this update",
    "subscriber": {
        "id": "urn:uuid:41b12f2d-1d92-438f-be5e-43a534158caf",
        "last_event_id": "",
        "remote_addr": "172.22.0.1:33614",
        "topic_selectors": [
            "https://example.com/users/foo/{?topic}"
        ],
        "topics": [
            "https://example.com/books/{id}"
        ]
    },
    "update": {
        "id": "urn:uuid:82b6cc3a-c202-491b-845a-041a1b29955d",
        "type": "",
        "retry": 0,
        "topics": [
            "https://example.com/books/1",
            "https://example.com/users/foo/?topic=https://example.com/books/1"
        ],
        "private": true,
        "data": ""
    }
}

Is there a bug in Mercure with this kind of use or am I doing something wrong ?

Thanks for your help !

Finally, there was probably a missing / in one of my topics. So everything works fine.
