Dataset not found:

Error message

Dataset not found: 

What it means

Thrown by DatasetVersionServiceImpl.create() when the parent dataset referenced by request.getDatasetId() does not exist (datasetMapper.selectById returns null). Versions can only be created for an existing dataset.

Solutions

1. Verify the dataset exists via the dataset get/list API before creating a version
2. Create the dataset first if it does not exist
3. Check the datasetId value (not a version id) is being sent
4. Confirm both operations run against the same database/environment

Example fix

// before
DatasetVersion v = datasetVersionService.create(req); // req.datasetId = 123 (never created)
// after
Dataset d = datasetService.getById(req.getDatasetId());
if (d == null) { d = datasetService.create(newDatasetRequest); req.setDatasetId(d.getId()); }
DatasetVersion v = datasetVersionService.create(req);

if (req.getDatasetId() == null || datasetService.getById(req.getDatasetId()) == null) { throw new BusinessException("parent dataset missing"); }

boolean canCreateVersion(Long datasetId) { return datasetId != null && datasetService.getById(datasetId) != null; }

try { versionService.create(req); } catch (IllegalArgumentException e) { if (e.getMessage().startsWith("Dataset not found")) { createDatasetThenVersion(req); } else { throw e; } }

When it happens

Trigger: Creating a version for a datasetId that was deleted, never created, or belongs to another environment/database.

Common situations: Client caches a dataset id after the dataset was removed; datasetId/versionId confusion; dev-vs-prod database mismatch; bulk-import scripts with fabricated ids.
