How to show docs with nginx url prefix set?

[almosthuman56]

I have project which uses flask-smorest and when I run it locally it shows docs on url /docs/swagger. But on my production server I have in nginx setup to append api/ prefix on each url and then docs are not showing because flask-smorest expects openapi.json on docs/openapi.json but mine nginx append api/ and openapi.json is visible on url api/docs/openapi.json so I keep getting error:

So basically how to setup configuration so it loads docs? Here are mine configuration in project for flask-smorest:

app = Flask(__name__)
app.config["API_TITLE"] = "Test API"
app.config["API_VERSION"] = "v1"
app.config["OPENAPI_VERSION"] = "3.0.2"
app.config["OPENAPI_URL_PREFIX"] = "/docs"
app.config["OPENAPI_REDOC_PATH"] = "/redoc"
app.config["OPENAPI_REDOC_URL"] = "https://cdn.jsdelivr.net/npm/[email protected]/bundles/redoc.standalone.js"
app.config["OPENAPI_SWAGGER_UI_PATH"] = "/swagger"
app.config["OPENAPI_SWAGGER_UI_URL"] = "https://cdn.jsdelivr.net/npm/[email protected]/"

api = Api(app)
api.register_blueprint(blp_test)

We most often deploy with nginx + uwsgi and setup uswgi to prepend API URLs with /api/v1 like explained here. I believe this is transparent to Flask so we don't have to do anything for this to work.

Out of curiosity, I'd try to use APPLICATION_ROOT, but I'm not sure it is the right thing to do.
