[oiwn]

Trying to install dash docsets using helm-dash-install-docstes

got error

Contacting host: api.github.com:443
helm-dash-available-docsets: Wrong type argument: integer-or-marker-p, nil

what could be wrong?

I just tried the latest version and works fine here. Only thing that occurs to me is that you didn't have internet connection and the response is invalid.... but not sure

[elheremes]

I've got the same problem too!

[kidd]

can you try with toggle-edebug-on-error ?

It seems the JSON containing list of docset is genereted via Github API, which has rate-limiting. Maybe this is the issue. Perhaps caching of this generated file would help (beyond mi lisp-fu :( )?
