CometAPI chat: is not valid for chat completion!

Error message

CometAPI chat: ${this.model} is not valid for chat completion!

What it means

Pre-flight guard in CometApiLLM.getChatCompletion: isValidChatCompletionModel(this.model) resolved false, meaning the configured model does not appear in CometAPI's known/cached model list, so a completion request would target a model the service does not offer.

Solutions

1. Select a model valid for chat completion in CometAPI settings.

When it happens

Trigger: Thrown when the configured CometAPI model is not a chat model.

Common situations: Model preference set to an embedding or invalid model.
