Graphorin API reference / @graphorin/provider / / readRetryAfterMs

Function: readRetryAfterMs()

function readRetryAfterMs(err): number | null;

Defined in: packages/provider/src/errors/retryability.ts:98

Stable

Read a Retry-After hint from a thrown error. Recognises:

• errors carrying a retryAfterMs field (already milliseconds) - RateLimitExceededError and ProviderHttpError with a numeric Retry-After response header both stamp it;
• errors carrying a retryAfterSeconds numeric field;
• HTTP-shaped errors carrying a headers['retry-after'] value (numeric seconds, or an HTTP-date resolved against the current clock).

Returns the resolved delay in milliseconds or null when no hint is available. withRetry consumes this to honour server-provided backoff over its own schedule.

Parameters

err	unknown

Returns

number | null
