No Data is Returned After Crawling (formats-JSON)

Export

Firecrawl: no Data is Returned After Crawling (formats-JSON). The verified fix is Contributor ftonato investigated with the reporter's real URLs and prompts: no API bug. Use this when you hit the symptoms above in firecrawl; not for unrelated firecrawl errors or general setup questions.

TL;DR

Contributor ftonato investigated with the reporter's real URLs and prompts: no API bug. The key factor was the reporter's maxDepth: 1 configuration differing from working setups, plus overly long/detailed extraction prompts confusing the LLM - break big extractions into smaller focused prompts.

The error

Crawl status shows 'completed' but returns an empty data array with formats ['json'] + jsonOptions prompt, where the same code worked the day before.

Fix

  1. Contributor ftonato investigated with the reporter's real URLs and prompts: no API bug.
  2. The key factor was the reporter's maxDepth: 1 configuration differing from working setups, plus overly long/detailed extraction prompts confusing the LLM - break big extractions into smaller focused prompts.
  3. Lesson: empty structured-extraction results are usually a config/prompt problem (check maxDepth and prompt size), not an outage.

Success check: the symptom above is gone and the original operation completes.
