Solutions

1. List groups via GET /admin/customer-groups to confirm the id
2. Handle 404 by routing back to the groups list
3. Verify backend URL/environment

const { customer_groups } = await sdk.admin.customerGroup.list({ id })
if (!customer_groups.length) throw new Error("group not found")

null

try { await getGroup(id) } catch (e) { if (e.statusCode === 404) navigate("/customer-groups") else throw e }

When it happens

Trigger: GET /admin/customer-groups/:id with a deleted or nonexistent group id.

Common situations: Group deleted while its detail page was open; stale links from notifications; environment mismatch.
