    Properties

    maxConcurrency?: number

    The maximum number of concurrent calls that can be made. Defaults to Infinity, which means no limit.

    maxRetries?: number

    The maximum number of retries that can be made for a single call, with an exponential backoff between each attempt. Defaults to 6.

    onFailedAttempt?: FailedAttemptHandler

    Custom handler to handle failed attempts. Takes the originally thrown error object as input, and should itself throw an error if the input error is not retryable.
