Error message

Error: assistantsController.updateAssistant - workspace ${workspaceId} not found!

What it means

Thrown by updateAssistant with HTTP 404 after the id and body guards pass, when req.user?.activeWorkspaceId is falsy. The service updateAssistant(id, body, workspaceId) requires a workspace to scope the update.

Solutions

Select/switch into a workspace, then retry the PUT.
Verify auth middleware populates activeWorkspaceId and workspace membership.

Defensive patterns

Strategy: try-catch

Type guard

const hasActiveWorkspace = (u: unknown): u is { activeWorkspaceId: string } =>
  !!u && typeof u === 'object' &&
  typeof (u as any).activeWorkspaceId === 'string' &&
  (u as any).activeWorkspaceId.length > 0

Try / catch

try {
  await updateAssistant(id, payload)
} catch (err) {
  if (err?.statusCode === 404 && /workspace .* not found/i.test(err.message)) {
    await selectWorkspace()
    return updateAssistant(id, payload)
  }
  throw err
}

Prevention

Ensure a workspace is selected before saving edits.
Handle workspace 404s with select-then-retry.
Verify workspace membership for the user.

When it happens

Trigger: Authenticated PUT /api/v1/assistants/<id> with a valid body, from a session with no activeWorkspaceId.

Common situations: Editing an assistant after the session lost its workspace context; user with no workspace membership.
