UX Turbo Mercure - Basic config returns 401

[jmsche]

Hi,

I've tried last week to set up a demo project, as simple as possible, to try UX Turbo with Mercure.

Unfortunately, I can't find a way to make this work.
The best I managed to get is a 401 Unauthorized response when the browser tries to connect to the Mercure server, while I seem to manage to connect to it correctly in my terminal using curl.

Here is the reproducer: https://github.com/jmsche/turbo-reproducer
You can read its README to launch it "easily" (using Symfony CLI & Docker Compose).

What I noted though: I don't see any token passed to the XHR request sent to Mercure.

Here is the request I got from Firefox (using right click on the request => copy as curl):

curl 'http://127.0.0.1:3010/.well-known/mercure?topic=chat' -H 'User-Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:87.0) Gecko/20100101 Firefox/87.0' -H 'Accept: text/event-stream' -H 'Accept-Language: fr,fr-FR;q=0.8,en-US;q=0.5,en;q=0.3' --compressed -H 'Origin: https://127.0.0.1:8000' -H 'Connection: keep-alive' -H 'Pragma: no-cache' -H 'Cache-Control: no-cache'

As you can see the request is sent to the correct URL/port; so Symfony CLI does not seem to be the issue here.

The problem is that you currently try to use an external hub while also using Symfony CLI. You need to use the built-in hub provided by Symfony CLI and the JWT key must be the default one (!ChangeMe!).

See https://github.com/symfony/cli/issues/424 for more details and a workaround.

The Symfony CLI built-in mercure hub has been removed (see https://github.com/symfony/cli/issues/449).
