Unfriendly Error Message When Updating Non-Existent Campaign via PUT /api/v1/settings/marketing/campaigns/{id}

Description:

When attempting to update a marketing campaign using an ID that does not exist, the API returns a 404 with an internal exception trace. This is not user-friendly and exposes internal paths and classes.

Affected Endpoint:

• PUT /api/v1/settings/marketing/campaigns/{id}

Preconditions:

• Campaign ID 34 does not exist in the system.

Steps to Reproduce:

1. Execute the following PUT request:

curl -X PUT 'http://<host>/api/v1/settings/marketing/campaigns/34' \
-H 'Accept: application/json' \
-H 'Authorization: Bearer <token>' \
-H 'Content-Type: application/json' \
-d '{
  "name": "Spring Sale",
  "subject": "Get Ready For Our Biggest Sale of the Year!",
  "status": "1",
  "marketing_template_id": "1",
  "marketing_event_id": "8"
}'

2. Ensure ID 34 does not exist.
3. Observe the server response.

Actual Result:

{
  "message": "No query results for model [Webkul\\Marketing\\Models\\Campaign] 34",
  "exception": "Symfony\\Component\\HttpKernel\\Exception\\NotFoundHttpException",
  ...
}

Expected Result:

• A clean error message:

{
  "message": "Campaign with ID 34 not found.",
  "status": 404
}
