OpenClaw 2026.4.29 renamed the per-model field from "label" to "name". The
old field is now an Unrecognized key, which fails schema validation at
gateway startup and exits OpenClaw before any HTTP listener binds.
Symptom (v2.1.0 first-launch):
- models.providers.uclaw-cloud.models.0.name: Invalid input: expected string, received undefined
- models.providers.uclaw-cloud.models.0: Unrecognized key: "label"
- throwInvalidConfig() at io-DaEsZ_NY.js:2901 -> process exit
Found via end-to-end H: drive test of v2.1.0 portable zip.
