InvalidModel

Error message

ResponseCode.InvalidModel

What it means

InvalidModel is thrown by RelayVideoService.createFromRequest when request.model does not match any configured video generation model, or when the supplied mode is not in the model's allowed modes list. The Relay channel only accepts models/modes explicitly declared in modelsConfigService.config.video.generation.

Solutions

1. Use a model name exactly matching an entry in the video.generation models config (check models config file/env for available names)
2. If the model should be supported, add it to modelsConfigService.config.video.generation and redeploy
3. Fetch the current model list from the API and populate client pickers from it instead of hardcoding
4. Confirm you are targeting the right channel: Relay-supported models differ from OpenAI/Dashscope ones

Example fix

// before
await relayVideoService.createFromRequest({ model: 'sora-2-pro', ... }) // not in relay config
// after
const models = modelsConfigService.config.video.generation.map(m => m.name)
await relayVideoService.createFromRequest({ model: models.includes('sora-2-pro') ? 'sora-2-pro' : models[0], ... })

const names = modelsConfigService.config.video.generation.map(m => m.name)
if (!names.includes(request.model)) {
  throw new Error(`Unknown relay video model: ${request.model}; available: ${names.join(', ')}`)
}

function isKnownRelayVideoModel(name: string, cfg: ModelsConfig): name is string {
  return cfg.video.generation.some(m => m.name === name)
}

try {
  await relayVideoService.createFromRequest(req)
} catch (e) {
  if (e instanceof AppException && e.code === ResponseCode.InvalidModel) {
    // refresh model list from config/API and prompt user to pick a valid model
  } else throw e
}

When it happens

Trigger: line 34: request.model is not found in modelsConfigService.config.video.generation (no entry whose name equals request.model).

Common situations: Typo in model name; model removed or renamed in the models config after a deployment; client using a model that only exists on OpenAI/Dashscope, not the Relay channel; stale cached model list on the client; config file/env not updated to add a newly available Relay model.
