# Event service PR pipeline fails with template not found

**One-sentence summary:** event-service repositories scaffolded on Forge 3.8.2 or earlier reference a pipeline template name that never existed; point the `extends:` block at the correct template.

---

## 🚨 Symptom

The PR validation pipeline for an event-service repository fails at queue time:

```text
Template reference not found: azure-event-service-pr-v2.yml@templates
```

Appears in Azure DevOps when a PR triggers `.azdo/azure-pipelines-pr.yml`.

---

## 📌 Applies to

| Aspect | Value |
| ------ | ----- |
| **Component** | Azure DevOps pipelines, `saif-event-service` template |
| **Forge versions** | Repositories scaffolded on 3.8.2 and earlier |
| **Related versions** | `SAIF/pipeline-templates` at `refs/heads/releases/v3` |

---

## 🧠 Cause

The `saif-event-service` template generated a pipeline that extends `azure-event-service-pr-v2.yml@templates`, but no template with that name exists in `SAIF/pipeline-templates`. The Forge template source has been corrected for future scaffolds, but existing repositories keep their generated file.

---

## ✅ Fix

In `.azdo/azure-pipelines-pr.yml`, update the `extends:` block:

```yaml
extends:
  template: azure-event-service-pr.yml@templates # was: azure-event-service-pr-v2.yml@templates
```

---

## 🔬 Verify

Push the change or re-queue the PR pipeline. The run starts instead of failing at template resolution.
