You don't have access to this dataset.

Error message

You don't have access to this dataset.

What it means

After a dataset is imported (or matched), import_dataset calls security_manager.raise_for_access(datasource=dataset) unless ignore_permissions is set. If the importing user lacks access to the dataset's database/schema/table per the RBAC/RLS rules, SupersetSecurityException is converted to DatasetAccessDeniedError ('You don't have access to this dataset.').

Solutions

1. Grant the importing user's role access to the target database (and schema/dataset) via Settings → Database / Roles, then retry
2. Import a bundle whose datasets reference databases the user can access
3. Run the import as a user with the appropriate data-access grants

from superset import security_manager
# pre-flight: confirm the current user can access every database referenced by the bundle
for cfg in dataset_configs:
    db = session.query(Database).filter_by(id=cfg['database_id']).first()
    security_manager.raise_for_access(database=db)  # raises before any import work

from superset.commands.dataset.exceptions import DatasetAccessDeniedError
try:
    import_dataset(config)
except DatasetAccessDeniedError:
    # grant database/schema access to the user's role, or import a bundle they can access
    ...

When it happens

Trigger: A user imports a bundle referencing a database or schema they have no 'database access'/'schema access' grant for (or RLS rules deny it); common when analysts import bundles built on data sources outside their grants.

Common situations: Importing example or shared bundles that point at restricted databases; role missing can_access on the target database; RLS rules rejecting the user on the dataset's table.
