Reference error when using import-mapping

[valensto]

Hi, hope you all are fine!

Trying to use a common schema for my project, but I've an error in swagger UI:

Resolver error at paths./users.post.responses.default.content.application/json.schema.$ref Could not resolve reference: undefined undefined

When I put all in the same file spec.yaml and generate it all work but if I try to separe Error schema to a common package I got this err

• common
• user

in a common folder I've only

components:
  schemas:
    Error:
      type: object
      properties:
        message:
          type: string

In user one

...
paths:
  /users:
    post:
      ...
      responses:
        '201':
          content:
            application/json:
              schema:
                $ref: '#/components/schemas/User'
        default:
          content:
            application/json:
              schema:
                $ref: '../common/spec.yaml#/components/schemas/Error'

components:
  schemas:
    User:
      type: object
      properties:
        id:
          type: integer
          format: int32
        lastname:
          type: string
        firstname:
          type: string
        created_at:
          type: string
          format: date-time

the User schema work but not the Error one, I don't have error when I generate only in the UI

the command line for user spec.yaml
oapi-codegen -generate types,skip-prune,spec,chi-server -package user -o ./user/openapi_types.gen.go --import-mapping=../common/spec.yaml:distrustia.com/main_api/api/common ./user/spec.yaml

the command line for the common spec.yaml

oapi-codegen -generate types,skip-prune,spec -package common -o ./common/openapi_types.gen.go ./common/spec.yaml

I tried to use the example provide about external ref but same problem

Found something in the openapi3 package from kin-openapi :
InternalizeRefs
I used it before render GetSwagger spec

spec, _ := api.GetSwagger()
spec.InternalizeRefs(context.Background(), openapi3.DefaultRefNameResolver)
s.Respond(w, r, http.StatusOK, spec)

Seem work for me as a swagger-cli bundle
