Ok, got it.
It was indeed the CSRF issue. I included that middleware to fix the issue.
For anyone else struggling with this, There's a *sente/example-project* with
some code
<https://github.com/ptaoussanis/sente/blob/master/example-project/src/example/my_app.cljx#L113>
that uses the csrf middleware.
But also in my case, I'm using austin's browser-repl. Now, sente's default
behaviour is to use the URL of your connected client. However, my connected
repl client is "172.28.128.5:*58269*", which is not the actual port of the
webserver. Http-kit defaults to port 8090, so I needed a URL of "ws://
172.28.128.5:*8090*/chsk". And sente let's you pass in a :chsk-url-fn,
letting you specify your own URL. And that's how I got around that problem.
Hope that's clear, and that it helps someone.
