After running, the following message is displayed
```
docker run -it --env-file=/docusaurus/algolia/.env -e "CONFIG=$(cat /docusaurus/algolia/config.json | jq -r tostring)" algolia/docsearch-scraper
> DocSearch: https://blog.pptfz.cn/ 0 records)

Crawling issue: nbHits 0 for pptfz
```

How should this problem be solved

Start by reproducing the documented docker run command with config.json and inspect the scraper output for why the crawl reports zero records. Done means the container successfully crawls the configured site and no longer reports nbHits 0 for the index.
