client not found for provider composite: %s

Error message

client not found for provider composite: %s

What it means

CreateChatCompletionWithInternalStream: the resolved providerComposite key is absent from the clients map, so no configured client exists for the model role's provider. Means missing API key/env var or an unsupported/unconfigured provider for this org.
