We are seeing an issue with the notification tray history endpoint where mention notifications sometimes return `targetName` as `”undefined”`, which also causes the `description` field to read awkwardly (e.g., “UserX has mentioned you in a comment in undefined”)

Here’s an example payload from our environment:

```auto
{
 "targetType": "comment",
  "verb": "mention",
  "targetName": "undefined",
  "parentTargetType": "post",
  "parentTargetId": "6862fd41020414d0a3f769d5",
  "targetId": "68b8a91565078eda567a5637",
  "actors": [{ "name": "TheWatchGuy" }],
  "description": "TheWatchGuy has mentioned you in a comment in undefined."
}

```

For comparison, here’s a case where it works correctly

```auto
{
  "targetType": "comment",
  "verb": "mention",
  "targetName": "Wrist Time",
  "parentTargetType": "post",
  "parentTargetId": "68a5d533de362aeea9ec6a01",
  "targetId": "68b88fac65078eda56775163",
  "actors": [{ "name": "MicroRotor7482" }],
  "description": "MicroRotor7482 has mentioned you in a comment in Wrist Time."
}

```

Questions:

1. Is `targetName` supposed to always resolve to the post/community name for mention notifications?
2. is there a recommended workaround to ensure `description` doesn’t come back with `”undefined”`?

Thanks in advance!

Hello @abrown1916 , Thank you for raising this issue and for providing the payload examples.

Our team suggests using the following endpoint instead for more reliable results:
