Error message

Vectors: Embeddings module missing

What it means

Thrown when source is 'extras' but the connected Extras API does not report 'embeddings' in its modules list. SillyTavern-Extras is modular; if the embeddings module is not enabled (or not installed), it cannot produce vectors.

Solutions

1. Restart SillyTavern-Extras with the embeddings module enabled (check its --enable-modules / config).
2. Verify the Extras base URL and API key in connection settings point at the right instance.
3. Confirm the modules list the server reports actually contains 'embeddings' (check the server response).
4. Switch the vector source to a built-in provider if you cannot run Extras embeddings.

Example fix

null

if (settings.source === 'extras') {
  const mods = Array.isArray(modules) ? modules : await fetchModules();
  if (!mods.includes('embeddings')) {
    // block; tell the user to enable the embeddings module in Extras
  }
}

null

null

When it happens

Trigger: Vector source set to 'Extras' while the Extras backend is running without the embeddings module enabled.

Common situations: Extras started without the embeddings flag/dependency; Extras process updated and the module name/availability changed; Extras connection points at a different instance that lacks embeddings.
