GET /get_allowed_conflations has a 200 response with no description, failing OpenAPI validation on the -es deployments

[gaurav]

The Elasticsearch-backed NodeNorm publishes a 200 response with no description, which OpenAPI 3.x requires on every response object, so the document fails validation:

'description' is a required property

Failed validating 'required' in schema['properties']['paths']['patternProperties']['^/']['else']
    ['properties']['get']['properties']['responses']['patternProperties']['^[1-5](?:[0-9]{2}|XX)$']['else']

The offender is GET /get_allowed_conflations, whose 200 response carries content but no description.

Affected (checked 2026-08-31), version 1.0.0 in both:

• https://nodenorm-es.test.transltr.io/webapp/openapi.json
• https://nodenorm-es.ci.transltr.io/webapp/openapi.json

The Redis-backed deployments do not have this problem; they fail validation for a different reason, filed separately as #409 (which the Elasticsearch document also carries).

To reproduce:

import requests
from openapi_spec_validator import validate
validate(requests.get("https://nodenorm-es.test.transltr.io/webapp/openapi.json").json())
