Relative references from a URL to a file in the parent folder throw error (OAS2)

[ymohdriz]

Hi team,

I have a file hosted in server say http://mcmriz01:5555/WmAPIGateway/validpath/service/serviceA.yaml in which refA.yaml (http://mcmriz01:5555/WmAPIGateway/validpath/refA.yaml) is referred
paths:
/test:
get:
responses:
'200':
schema:
$ref: '../refA.yaml'

Error: Unable to load RELATIVE ref: ../refA.yaml
Note: This is not working when the input is url, works fine for a input file

Thanks,
Mohammed

Hi, @ymohdriz which version of parser are you using?

[gracekarina]

Hi @ymohdriz can you please try one of these branches to test your issue?
version 2.0 = fix-relative-resolving (depends on core's ref-refactor branch)
version 3.0 = OAS3-relative-resolving

Hi, is this still an issue? @ymohdriz

@gracekarina, I was bitten by this error right now. I'm using a GitLab's private repository to get the root spec.
But the relative $ref is being concated into the resolved root url.

Hi @cvgaviao, please send a spec or a sample where we can reproduce and test the issue. Thanks!

Hi @cvgaviao, please send a spec or a sample where we can reproduce and test the issue. Thanks!

@gracekarina, I've found that the issue I'm facing is not spec dependent.

It is caused by the way we mount a URL to access a spec hosted in a Gitlab's private repository. see a better description here
