TextGenWebUI must have a valid base path to use for the api.

Error message

TextGenWebUI must have a valid base path to use for the api.

What it means

Configuration guard thrown by the TextGenWebUILLM constructor: TEXT_GEN_WEB_UI_BASE_PATH is empty/unset, so the adapter has no URL for the local text-generation-webui API server and the OpenAI-compatible client cannot be initialized.

Solutions

1. Set the TextGenWebUI base path in provider settings.

When it happens

Trigger: Thrown at provider construction when no base path is configured.

Common situations: TextGenWebUI selected without a base path.
