Semantic view does not exist

Error message

Semantic view does not exist

What it means

Raised by DeleteSemanticViewCommand.validate() (superset/commands/semantic_layer/delete.py:84) when SemanticViewDAO.find_by_id(self._pk, id_column="id") returns None. The single-view delete looks the view up by integer primary key; if no row matches, SemanticViewNotFoundError is raised before any authorization or deletion happens.

Solutions

1. Confirm the id exists via the list/detail API before deleting
2. Handle 404 as idempotent success when the end goal is removal
3. Make sure you pass the integer 'id' field, not the view's 'uuid', to the delete endpoint

from superset.daos.semantic_layer import SemanticViewDAO

if SemanticViewDAO.find_by_id(view_id, id_column="id") is None:
    raise LookupError(f"view {view_id} already gone")

try:
    DeleteSemanticViewCommand(view_id).run()
except SemanticViewNotFoundError:
    pass  # already deleted; treat as success

When it happens

Trigger: DELETE on the semantic view endpoint with an integer id that does not exist; the view was removed by a concurrent request between the client loading the list and issuing the delete.

Common situations: Stale UI grid after another user deleted the view, replaying an old request, or passing a UUID where the integer id is expected.
