Workspace does not have search configured

Error message

Workspace does not have search configured

What it means

The index route (POST /workspaces/:workspaceId/index) throws this 400 when the target workspace has neither BM25 nor vector search enabled (workspace.canBM25 and workspace.canVector are both false). Content can only be indexed if the workspace was configured with at least one search backend.

Solutions

1. Configure the workspace with BM25 and/or vector search enabled (per workspace options) before indexing.
2. If search is not needed, don't call the index endpoint.
3. Verify server-side why canBM25/canVector are false (missing index path, missing embedder/vector store config, env vars).
4. Restart/redeploy the server after adding search configuration.

Example fix

// before
new Mastra({ workspaces: { ws1: createWorkspace({ filesystem: fs }) } });
// after
new Mastra({ workspaces: { ws1: createWorkspace({ filesystem: fs, search: { bm25: { enabled: true } } }) } });

// Capability check via the search endpoint's configured workspace
const list = await fetch(`/api/workspaces/${wsId}/search?query=probe`).then(r => r.json());
// or check server config exposes canBM25/canVector before indexing

function supportsSearch(ws: { canBM25?: boolean; canVector?: boolean }): boolean {
  return Boolean(ws.canBM25 || ws.canVector);
}

try {
  await indexContent(wsId, path, content);
} catch (e) {
  if (isHTTPException(e, 400) && /search configured/.test(e.message)) {
    // skip indexing or enable BM25/vector in workspace config and redeploy
  } else throw e;
}

When it happens

Trigger: POSTing content to /workspaces/:id/index on a workspace constructed without a BM25 index directory or vector store; indexing before search backends are initialized; calling index on a filesystem-only workspace.

Common situations: Deploying a workspace config where search options (BM25/vector) were omitted; assuming default search is enabled; environment lacks the index directory or vector DB config so the workspace reports no search capability; stale client docs assuming old defaults.
