## TL;DR
Rebuild the mapping between internal services and public component groups, check for renamed or duplicated components, and preview the public page as a customer. Do this before posting workarounds to customers: confirm the fault in customer status page, fix the single mismatched value or setting described in the steps, then repeat the original action and check the public page as a logged-out visitor. Most cases of this error are a configuration or value mismatch in component group mapping, not a provider outage, so a methodical check clears it in minutes.

customer status page shows wrong component group: mapping failed error fix
```

## Use this when
- The exact error above appears while working with component group mapping during an incident or a test incident.
- The public status page does not reflect what responders saved in customer status page.
- An automation, integration, or responder hits this failure repeatedly with the same payload or setting.
- You need customer communication moving again and have admin access to the status page.

## Not for this skill when
- customer status page reports a confirmed platform outage on its own status page. Wait for the provider and post a holding update instead.
- You are designing a new status page or choosing between providers. This skill only repairs the named failure.
- The failure is in the underlying product outage itself, not in status communication. Fix the product incident first.

## Steps
1. Reproduce the failure once and capture the exact request, response, and timestamp from customer status page. Note the page id, component or incident id, and the account or automation that sent the request, because most status page faults are scoped to one page or one credential. Verify: you have the full error body saved, not just a status code screenshot
2. List public components and groups side by side with internal service names. Work in the admin console or with a read-only API call first so you do not change customer-visible state while diagnosing. Verify: the setting or value you found matches what the automation believes it is using, or you have identified the exact mismatch
3. Fix assignments for renamed or duplicated components and save the group layout. Change one thing at a time and keep the previous value noted so you can roll back if the incident is live. Verify: the change is saved in customer status page and visible on a fresh page load, not only in the editor
4. Preview the page logged out and confirm each group shows the intended components. Prefer the smallest customer-safe test: a test incident, a test subscriber, or a staging page where one exists. Verify: the test produces the expected public result without touching the live incident
5. Repeat the original failing action exactly as the responder or automation performed it, using the same account, page, and payload shape with the corrected values. Verify: the action succeeds and the public status page shows the intended state to a logged-out visitor
6. Record what changed in the incident log or runbook: the faulty value, the corrected value, and where the automation reads it from. Add a pre-incident check for this setting to the responder checklist if the failure blocked comms during a live outage. Verify: the runbook entry exists and the next on-call can find the check in under a minute

## Why it happens
Public groups are a curated mapping, not a mirror. Renamed services, duplicate components, or a group assignment saved on the wrong page make the customer view show the wrong group. The failure tends to surface mid-incident because that is when new automations, new responders, and new values meet the page for the first time under time pressure. Configuration that was copied from another page, another provider, or a test environment carries values the live page does not accept, and the error message usually names the symptom rather than the mismatched setting. Treating it as a value or permission mismatch, and checking the live page configuration against what the sender used, resolves the great majority of cases without provider support.

## Variants and edge cases
### customer status page shows wrong component group - variant with a different tool in the chain
The same failure arriving through an integration (for example a bridge from an incident tool) instead of the admin console. Diagnose on the customer status page side first, because the bridge usually collapses the real error into a generic one, then fix the mapping or credential the bridge uses.

### Same error on a second page or staging page
Multi-page accounts repeat this fault when configuration is copied between pages. Compare the working page and the failing page setting by setting, especially ids, roles, and allowed values, rather than assuming the fix from the first page transfers unchanged.

### Error returns after working for weeks
A sudden recurrence usually means a rotation, rename, or cleanup changed the underlying value: a key was rotated, a component renamed, a template edited, or a group membership changed. Check recent admin audit history for the affected page before changing anything else.

Compatibility: Applies to customer status page current web console and API as of October 2026, and to common bridges from PagerDuty, Opsgenie, Slack, Datadog, and incident tools that publish to it. Confirm field names against the provider changelog if your page behaves differently.
