synapse returns 500 error on HEAD requests #2029

majewsky · 2017-03-18T20:49:07Z

I set up Synapse 0.19.2 on my server (here's the configuration that I use). Once I got it to start, the first check that I did was:

$ curl https://bethselamin.de/_matrix      

<html>
  <head><title>405 - Method Not Allowed</title></head>
  <body>
    <h1>Method Not Allowed</h1>
    <p>Your browser approached me (at /_matrix) with the method "GET".  I only allow the method HEAD here.</p>
  </body>
</html>

So I did:

$ curl --head https://bethselamin.de/_matrix
HTTP/1.1 500 Internal Server Error
...

And there's a stacktrace in the systemd journal:

I am not a developer, but https://bethselamin.de/_matrix/client/# worked in my case.

a) it's bueller; b) this is a really superficial/cosmetic error and it really shouldn't be surprising that we prioritised it way below actually making synapse work reliably & performantly...
