Hi,
we just upgraded from oapi-codegen 2.3.0 to 2.5.1 and our go code generated from OpenAPI isn't valid anymore. I pinned down the issue to response components being referenced in endpoints and came up with this minimal reproducible spec:
openapi: 3.0.3
info:
title: test
version: 1.0.0
servers:
- url: https://te.st
paths:
/v1/test:
get:
operationId: GetTest
responses:
"200":
$ref: "#/components/responses/Success"
"401":
$ref: "#/components/responses/Unauthorized"
components:
responses:
Success:
description: Success
content:
application/json:
schema:
type: string
Unauthorized:
description: Unauthorized
content:
text/plain:
schema:
type: string
example: "Unauthorized"
We execute oapi-codegen with this configuration:
package: test
output: api.gen.go
generate:
std-http-server: true
strict-server: true
models: true
client: true
output-options:
nullable-type: true
The generated go code contains this:
type UnauthorizedTextResponse string
type GetTest401TextResponse struct{ UnauthorizedTextResponse }
func (response GetTest401TextResponse) VisitGetTestResponse(w http.ResponseWriter) error {
w.Header().Set("Content-Type", "text/plain")
w.WriteHeader(401)
_, err := w.Write([]byte(response))
return err
}
which is invalid as response is of type GetTest401TextResponse and cannot be converted to []byte.
We are using Go version 1.25.7.
I would appreciate if you could have a look, would also be happy to contribute.
Cheers
