Gitlab can not show divied v3 openapi schema on web
Now I’m in trouble about openapi preview on web viewer. Gitlab has swagger preview feature on file preview but it looks it does not support $ref dividing. Other tools and swagger-tool can read/preview/merge this file so I feel this is due to the version of gitlab’s swagger-ui or somethingthing. More on forum.gitlab.com

December 23, 2024 -

I know this may be a dumb question, but is there any chance gitlab has its OpenAPI/swagger json built into gitlab itself? I.E. on an offline instance I can go to something like https://gitlab.example.com/api/v4/swagger.json? I l am trying it pull the API definitions for our suite of applications for security purposes.

I had found the online version and yeah sure I could pull the spec from gitlab.com, but getting that file moved to the offline environment where it is needed is... troublesome. I'm also not going to hand transcribe it because I'm an engineer not a data entry clerk.
