Common Errors & Troubleshooting

{success: false} Invalid action name or malformed API endpoint path
✓ Use valid CKAN API actions like package_list, package_show?id=DATASET_ID, or datastore_search?resource_id=RESOURCE_ID
Empty result set The dataset may have been removed or updated with a different resource ID
✓ Re-fetch the package_show endpoint to get the latest resource IDs for your dataset
Slow response or timeout Some large GIS datasets can take several seconds to load
✓ Use the limit and offset parameters to paginate results, e.g. ?limit=100&offset=0
