@last_description nil in

[nonnenmacher]

recently got error :
in lib/grape-swagger.rb:96:in setup': undefined methodmerge!' for nil:NilClass (NoMethodError)

in create_documentation_class:setup
the culprit is line

        @last_description.merge!(api_doc)

I don't know what changed, but would it be safer to initialise @last_description to an empty hash
before merging, in case this member is not previously set properly / as expected ?

note : after making some safe guard I got other errors, in mounting API.
But after debugging, it seems that there is ongoing PR that aren't completed around removing Endpoint.settings.

      def combine_namespaces(app)
          app.endpoints.each do |endpoint|
               ns = endpoint.settings.stack.last[:namespace]

where settings is no longer a member of an Endpoint.

So I guess, this is not a grape-swagger issue, but a transient problem around this unfinished PR.

see here : ruby-grape/grape#712 and ruby-grape/grape#719

reverting to Grape 0.9.0 work.

Good luck for the upgrade ;-)

This has probably been introduced in ruby-grape/grape#739 on Grape/HEAD. Grape-swagger "knows" about some Grape internals, we need to refactor our way of that into using a more standard interface.

@last_description does not appear to be read from anywhere in the code. are the two references in grape-swagger.rb just orphans of a refactoring?

Likely.
