Failed to get vector: ${error instanceof Error ? error.messa

Error message

Failed to get vector: ${error instanceof Error ? error.message : String(error)}

What it means

Catch-all around Cloudflare Vectorize getByIds: fetching a single vector by id failed (auth, network, index/account mismatch, or an unexpected response shape), and the error is rethrown wrapped as 'Failed to get vector: <message>'. A normal 'not found' returns null instead — this error means the API call itself failed.

Solutions

1. Check the inner message; 401/403 -> grant the token Vectorize:Read (edit) permission.
2. Confirm indexName and accountId match the Cloudflare dashboard values.
3. Retry on transient 5xx/network errors — get is a read and safe to retry.

try { return await memory.get(id); } catch (e) { const m = e instanceof Error ? e.message : ''; if (m.startsWith('Failed to get vector:')) { if (isTransientInner(m)) return retryWithBackoff(() => memory.get(id), 2); /* missing id is null, not this error */ throw new Error(m); } throw e; }

When it happens

Trigger: memory.get(id) when the API token lacks read permission; indexName deleted; accountId wrong; network error during the REST call; Cloudflare API returning 5xx.

Common situations: Token scoped with Vectorize Write but not Read; pointing at another account's index; transient Cloudflare outages.
