Common Errors & Troubleshooting

Dataset not in JSON format Many Berlin datasets are published as CSV or shapefile, not JSON
✓ Check the resource format field in the package metadata before attempting to parse the download as JSON
Empty results from package_search The search query uses German keywords which may not match English terms
✓ Use German language keywords in your search query, for example Verkehr for traffic or Bevoelkerung for population
Resource URL returns 404 Dataset file URLs in the catalog may become outdated as files are updated
✓ Always fetch the package metadata first to get the latest resource URL rather than hardcoding file links
