Type " " is not a valid type to sync.

Error message

Type "${type}" is not a valid type to sync.

What it means

Thrown by PineconeDB.connect() when process.env.VECTOR_DB is not exactly the lowercase string 'pinecone'. AnythingLLM instantiates one vector provider per app, and each provider self-guards so it cannot be used while the app is configured for a different backend. The throw happens before any Pinecone SDK call, so nothing leaves the process.

Solutions

1. Set VECTOR_DB=pinecone in server/.env (exact lowercase) alongside PINECONE_API_KEY and PINECONE_INDEX, then fully restart the server/container so the env is re-read.
2. Log process.env.VECTOR_DB from the exact process that instantiates PineconeDB to confirm which .env file was loaded and that the value has no whitespace/case issues.
3. If you intentionally run a different VECTOR_DB, stop calling the Pinecone provider — check that the vector-db factory and any direct imports match your configuration.
4. Add a fail-fast boot check: if VECTOR_DB=pinecone, assert PINECONE_API_KEY and PINECONE_INDEX are non-empty before the app starts serving.

Example fix

# before (server/.env)
VECTOR_DB=lancedb
PINECONE_API_KEY=pc-...
PINECONE_INDEX=my-index

# after (server/.env)
VECTOR_DB=pinecone
PINECONE_API_KEY=pc-...
PINECONE_INDEX=my-index
# then restart: docker compose down && up, or restart `yarn dev:server`

const isPineconeSelected = () => process.env.VECTOR_DB === 'pinecone';
const pineconeConfigComplete = () =>
  isPineconeSelected() &&
  Boolean(process.env.PINECONE_API_KEY) &&
  Boolean(process.env.PINECONE_INDEX);

if (!pineconeConfigComplete()) {
  // do not call PineconeDB methods; VECTOR_DB is unset or another provider is active
  throw new Error(`Vector provider misconfigured: VECTOR_DB=${process.env.VECTOR_DB ?? 'unset'}`);
}

function isPineconeEnv(env = process.env) {
  return (
    env.VECTOR_DB === 'pinecone' &&
    typeof env.PINECONE_API_KEY === 'string' &&
    env.PINECONE_API_KEY.length > 0 &&
    typeof env.PINECONE_INDEX === 'string' &&
    env.PINECONE_INDEX.length > 0
  );
}

try {
  await vectorDB.heartbeat();
} catch (e) {
  if (/Invalid ENV settings/.test(e.message)) {
    // permanent config error — fix .env and restart; do NOT retry
    throw new Error('Set VECTOR_DB=pinecone in server/.env and restart the server');
  }
  throw e;
}

When it happens

Trigger: Any code path that reaches PineconeDB.connect() (heartbeat, totalVectors, addDocumentToNamespace, namespace-stats, delete-namespace, performSimilaritySearch) while VECTOR_DB is unset or set to 'lancedb' (the default), 'chroma', 'qdrant', 'weaviate', 'milvus', 'pgvector', etc. Also triggered by importing/instantiating PineconeDB directly in a script that does not load server/.env.

Common situations: Adding PINECONE_API_KEY/PINECONE_INDEX to .env but forgetting VECTOR_DB=pinecone; editing .env without restarting the Node process or Docker container; VALUE case mismatch ('Pinecone'); stray quotes/whitespace in the env value; a test or utility script run with a different dotenv path than the server.
