[bug] ics export is broken
Instead of an ICS, it returns a json with a 401 code.
It looks an issue with tags:
"categories[0] must be a `string` type, but the final value was: `{\n \"tag\": \"\\\"hort\\\"\"\n}`."
You can try it at https://bcn.convoca.la/feed/ics?tags=hort
or:
curl https://bcn.convoca.la/feed/ics?tags=hort https://bcn.convoca.la/feed/ics?tags=hort | json_pp
