Grape 0.9.0 and grape-swagger 0.9.0 incompatible

[asinghrails]

I am using Grape gem with rails app but I am getting below error when I call grape-swagger UI.

Error : Unable to read api 'users' from path https://appname.herokuapp.com/api/swagger_doc.json/users.json (server returned undefined)

Gem:: grape 0.9.0, grape-entity 0.4.4, grape-swagger 0.9.0, rails 4.1.6, rack-cors 0.2.9

Please help me

Does that endpoint work? Does it work without .json?

[asinghrails]

No. It is not working without json too.
I am getting this type of error, please have a look.

I am 99% sure this is a known bug fixed in the combination of grape 0.10.1 and grape-swagger 0.9.0, you should upgrade, but this is still an issue for the version combination of 0.9.0's.

[asinghrails]

Now I am using below version.
Using grape 0.10.1
Using grape-entity 0.4.4
Using grape-swagger 0.9.0

[asinghrails]

Still it is working with below version.
gem 'grape', '> 0.7.0'
gem 'grape-swagger', '> 0.7.2'
Thanks

Are you saying this is not working with 0.10.1 / 0.9.0 for you?

I could really use a repro, maybe on top of https://github.com/dblock/grape-on-rack?

[aaronrenner]

I ran into this issue as well. Here is a rails app that reproduces the problem: https://github.com/aaronrenner/ember-contacts-backend-demo/tree/grape-swagger-issue. Fire up the rails server and visit http://localhost:3000/documentation Since I'm continuing to work on the app, make sure to check out the grape-swagger-issue tag so you can reproduce it.

@aaronrenner Just change https://github.com/aaronrenner/ember-contacts-backend-demo/blob/master/config/initializers/grape.rb#L1 from

GrapeSwaggerRails.options.url = '/api/v1/swagger_doc.json'

to

GrapeSwaggerRails.options.url = '/api/v1/swagger_doc'

And everything will work. PR: aaronrenner/ember-contacts-backend-demo#1

Can everyone on this thread check this and confirm?

I changed https://github.com/tim-vandecasteele/grape-swagger/blob/master/UPGRADING.md.

[aaronrenner]

That works. Thanks @dblock.

[nguyenchiencong]
