caddy-json-schema: unexpected end of JSON input

That’s weird. Looks like something is wrong with the site for those docs (JS errors) – sigh, sorry about that. I will have to look into that as soon as I have a chance. (And I’ve noticed some docs where the yellow box explaining where the non-standard module’s repo can be found is missing… hmm.)

Fixed in https://github.com/abiosoft/caddy-json-schema/pull/8 You can test it out using my fork https://github.com/fedorg/caddy-json-schema It contains build instructions for Docker and a gist with the generated schema file.

Was going to note that I was still hitting this when generating the schema for 2.5.0 but I see now that there’s a PR to fix it which is great. If anyone is keeping track of which plugins have this doc issue, I hit it for all 3 of the ones I mentioned before plus one new one. Here’s the current list of the plugins I had to manually fix docs.json for:

• apps/http.handlers.prometheus
• apps/http.handlers.request_debug
• apps/http.handlers.image_filter
• apps/http.handlers.olaf

Running into this when building docs for https://github.com/mholt/caddy-l4.

I’m not a Go or Caddy expert, so maybe I’m doing something wrong?
