InvalidModel

Error message

ResponseCode.InvalidModel

What it means

InvalidModel thrown by VideoService.requireChannel when the channel-specific video service (e.g. relayVideoService) is not available/injected. The generic video facade requires the target channel's service to be registered; if the optional dependency is undefined, the requested model's channel cannot be served.

Solutions

1. Enable/register the missing channel service (import the Relay video module or set the enabling env/config)
2. Pick a model whose channel service is available in this deployment
3. Check that @Optional() RelayVideoService is actually provided in the module providers list
4. Verify models config doesn't advertise channels the deployment can't serve

Example fix

// before (module)
providers: [VideoService] // RelayVideoService missing
// after
providers: [VideoService, RelayVideoService]
// or guard the caller
const service = channel === 'relay' ? relayVideoService : dashscopeVideoService
if (!service) throw new AppException(ResponseCode.InvalidModel)

const service = channel === 'relay' ? relayVideoService : dashscopeVideoService
if (!service) {
  throw new Error(`Channel service unavailable for model ${model}; enable/register the channel module`)
}

function channelAvailable<T>(s: T | undefined | null): s is T {
  return s !== undefined && s !== null
}

try {
  await videoService.userVideoGeneration(req)
} catch (e) {
  if (e instanceof AppException && e.code === ResponseCode.InvalidModel) {
    // fall back to a model whose channel is registered, or surface 'channel not enabled in this deployment'
  } else throw e
}

When it happens

Trigger: userVideoGeneration, extractInput, or getChannelTaskResult resolve the channel service via requireChannel(service) and the service is undefined — e.g. RelayVideoService is @Optional() and not provided because the Relay module/config is disabled or missing.

Common situations: Relay feature flag/env var not enabled in this deployment; module not imported so the provider isn't registered; requesting a model whose channel maps to a service that isn't configured; DI misconfiguration after refactoring.
