For Apify SDK for JavaScript version 3.7.2, under which storage failures can Actor.setValue reject, and does that rejection propagate to the awaiting caller?
💡 Result:
In Apify SDK for JavaScript version 3.7.2, the Actor.setValue function acts as a wrapper for KeyValueStore.setValue [1][2]. Because it returns the promise from KeyValueStore.setValue, any rejection encountered during the operation propagates to the awaiting caller [3][1]. The function can reject under the following storage-related or operational failures: 1. Serialization Errors: If no options.contentType is specified, the SDK attempts to stringify the provided value to JSON [1][4]. If this process fails (for example, with an "Invalid string length" error for extremely large objects), the promise will reject [5]. 2. Validation Errors: When storing data in a key-value store with a defined schema or strict content type requirements, the Apify platform will reject the operation if the data does not conform to those specifications [6]. 3. Invalid Input Type: If options.contentType is explicitly set, the value must be a String or Buffer. The SDK will throw an error (resulting in a rejected promise) if any other data type is provided [3][1]. 4. Connection or API Errors: As Actor.setValue communicates with the underlying storage (either local disk or the Apify platform API), any network issues, authentication failures, or platform-side storage errors during the request will cause the promise to reject [7]. Because Actor.setValue returns a Promise, you must use the await keyword or attach a .catch() block to properly handle these rejections [3]. Failure to do so can result in unhandled promise rejections, and if the actor process finishes before the store operation completes, data may be lost [3].

Keep TIP persistence best-effort.
storeActorTip awaits Actor.setValue, so storage failures reject both unguarded calls. A rejection at line 79 prevents Actor.fail; a rejection at line 82 prevents normal completion. Catch and log TIP storage errors without changing the crawl result.

In normal mode the Actor now writes an advisory record under the reserved KVS key
TIPwhen the query or URL targets a site that has a dedicated Actor:{ "message": "For scraping tiktok.com, we recommend using TikTok Scraper", "level": "info" }
Covers exactly the sites listed in the issue. Matches both plain URLs and domains mentioned in a search query (
site:instagram.com nike).Note: the record is stored after the crawl. Crawlee purges the default storages while the crawlers start up, so a write placed before that is silently lost.
Closes #141.
