Group not found

Error message

Group not found

What it means

CreateLearningOutcomeGroup#get_group looks up LearningOutcomeGroup.active.find_by(id:) and raises 'Group not found' when nil. Like error 151, only active (non-deleted) groups count; missing, deleted, or cross-shard IDs all fail.

Solutions

1. Confirm the group ID exists and workflow_state is 'active' via a prior GraphQL lookup.
2. Re-select the parent group in the UI instead of relying on cached IDs.
3. Ensure the request is executed on the correct shard for the group.
4. Omit the parent id only if the mutation supports root-level creation for your context; otherwise always pass a verified id.

Example fix

// before
await gql(createLearningOutcomeGroup, { input: { parentGroupId: cachedId } })
// after
const parent = await gql(getOutcomeGroup, { id: cachedId })
if (!parent || parent.workflowState !== 'active') throw new Error('Pick a valid parent group')
await gql(createLearningOutcomeGroup, { input: { parentGroupId: cachedId } })

const parent = groupId ? await gql(GET_OUTCOME_GROUP, { id: groupId }) : null
if (groupId && (!parent || parent.workflowState !== 'active')) throw new Error('parent group not found')

function isResolvableActiveGroup(g) { return g != null && g.workflowState === 'active' }

try {
  await gql(CREATE_OUTCOME_GROUP, { input })
} catch (e) {
  if (e.message === 'Group not found') openGroupPicker()
  else throw e
}

When it happens

Trigger: Calling createLearningOutcomeGroup with parent_outcome_group_id pointing to a nonexistent, soft-deleted, or other-root-account group; omitting the id when the mutation requires nesting under an existing group.

Common situations: UI kept a stale parent group after deletion; syncing groups across environments; passing a course-level group ID where an account-level one is expected.
