vacuum: Remote references in components/schemas fail to resolve

I have a openapi spec that works fine on https://editor.swagger.io/ that throws errors with vacuum.

Remote references in paths/.../schema seem fine, but not in components/references/whatever are not.

I can’t figure out how to modify the libopenapi tests in ways that don’t crash, so I dunno if the issue is with them or not.

The spec:

{             
  "openapi": "3.0.0",
  "info": {       
    "version": "1.0.0",
    "title": "demo thing",
    "description": "demo thing"
  },      
  "paths": {
    "/a": {
      "get": {
        "responses": { 
          "200": {
            "description": "uses an external ref directly",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "https://raw.githubusercontent.com/pb33f/libopenapi/main/test_specs/petstorev3.json#/components/schemas/Pet"
                }
              }
            }
          }
        }
      }
    },
    "/b": {
      "get": {
        "responses": {
          "200": {
            "description": "uses a thing in components/schemas",
            "content": {
              "application/json": {
                "schema": {
                  "$ref": "#/components/schemas/SomeThing"
                }
              }
            }
          }
        }
      }
    }
  },
  "components": {
    "schemas": {
      "SomeThing": {
        "$ref": "https://raw.githubusercontent.com/pb33f/libopenapi/main/test_specs/burgershop.openapi.yaml#/components/requestBodies/BurgerRequest"
      }
    }
  }
}

This results in the error:

cannot resolve reference https://raw.githubusercontent.com/pb33f/libopenapi/main/test_specs/burgershop.openapi.yaml#/components/requestBodies/BurgerRequest, it's missing: $https:.['raw.githubusercontent.com'].pb33f.libopenapi.main.test_specs['burgershop.openapi.yaml$'].components.requestBodies.BurgerRequest

If you switch the URLs it still only fails on the SomeThing ref.

I’m running with npx vacuum lint --base . -d $specFile, and I have vacuum version 0.3.13
