Source annotation {source_annotation_id} not found in the cu

Error message

Source annotation {source_annotation_id} not found in the current project

What it means

propagate_annotations copies a source annotation's results to other tasks in the project. It looks up Annotation.objects.filter(project=project, id=source_annotation_id) from request.data and raises DataManagerException if no annotation matches, i.e. the id is absent, malformed, or belongs to another project.

Solutions

1. Fetch a valid annotation id from the project first (GET annotations for the source task) and pass it as source_annotation_id
2. Confirm the annotation belongs to the same project as the action's project parameter
3. Handle the DataManagerException client-side and re-select a source annotation

Example fix

// before
POST {"action": "propagate_annotations", "source_annotation_id": 99999}  // not in project
// after
const id = sourceTask.annotations[0].id;
POST {"action": "propagate_annotations", "source_annotation_id": id}

const ann = await api.getAnnotation(projectId, sourceAnnotationId);
if (!ann || ann.project !== projectId) {
  throw new Error(`Annotation ${sourceAnnotationId} not in project ${projectId}`);
}

function isAnnotationInProject(ann, projectId) { return ann != null && ann.project === projectId; }

try {
  await dm.addAction({id: 'propagate_annotations', source_annotation_id: id});
} catch (e) {
  if (String(e).includes('not found in the current project')) {
    await reselectSourceAnnotation();
  } else throw e;
}

When it happens

Trigger: Calling the propagate_annotations DataManager action without 'source_annotation_id' in request.data, with a nonexistent id, or with an id from a different project; stale id after the annotation was deleted.

Common situations: Client caches an annotation id that was later deleted; cross-project UI copy-paste; missing payload field; id passed as string vs int confusion is not an issue here but wrong-project ids are.

Understand the failure class

Background: 'Could not be found', 'does not exist', 'not found in database': the resource-not-found family when an ID, slug, key, or URI lookup comes back empty — this error's family across 20 libraries.
