This bug also extends to CRD from spec V1. It also seems to be that this condition is triggered for all CRD model generation.

eg. crd for external-secrets operator

kcl-openapi generate model --crd \
  -f <(curl -sS "https://raw.githubusercontent.com/external-secrets/external-secrets/main/config/crds/bases/external-secrets.io_externalsecrets.yaml") \
  --skip-validation

could not generate swagger spec: /dev/fd/11, err: no openapi schema found in the crd file. Please check following fields: spec.Validation.OpenAPIV3Schema, spec.Versions.0.Schema
