Failed to insert vectors: ${error instanceof Error ? error.m

Error message

Failed to insert vectors: ${error instanceof Error ? error.message : String(error)}

What it means

Generic catch wrapper around the Vectorize insert path: any thrown error (including the non-ok HTTP error, network failure, or TypeError while building the request) is logged and rethrown wrapped as 'Failed to insert vectors: <message>'. The inner message identifies the real cause — treat this as the outer envelope of error 313 plus network/serialization failures.

Solutions

1. Inspect the wrapped message — it contains the underlying cause; apply the matching fix (auth, index name, dimensions).
2. For transient network/5xx causes, retry the add operation with backoff (idempotent if you control the memory id).
3. Rotate the API token if the inner message indicates 401/invalid credentials.

const isTransient = (m: string) => /timeout|ECONNRESET|5\d\d/.test(m);
try { await memory.add(text); } catch (e) { const m = e instanceof Error ? e.message : String(e); if (m.startsWith('Failed to insert vectors:') && isTransient(m)) await retryWithBackoff(() => memory.add(text), 3); else throw e; }

When it happens

Trigger: Any exception during memory.add() on Cloudflare Vectorize: DNS/network failure reaching api.cloudflare.com, a fetch TypeError, an expired token producing 401 from the inner throw, or a dimension mismatch surfaced through the inner error.

Common situations: Transient network issues in serverless environments; expired or rotated Cloudflare API tokens; intermittent Cloudflare API 5xx responses.
