When I click on links to pipeline functions on the index page I get link not found - in this case it’s for parse_json() but others are broken too. Doesn’t seem to matter if it v4 or v5. Not all of them are broken, but quite a few are.
parse_cef() is a function available in the short docu in Graylog, but not in the big index in the docs as well.
I noticed that also, been getting 404 when clicking any links lately.
