# Error (#100) The action is invalid because it is not the topic owner

When replying to Instagram messages through SprintHub, the following error may occur:

```json
{
  "status": 400,
  "message": "Request failed with status code 400",
  "url": "xxxxx",
  "method": "POST",
  "data": {
    "success": false,
    "msg": "The action is invalid since it's not the thread owner."
  },
  "requestErros": []
}
```

Or the message:

> **Error (#100) The action is invalid because it is not the owner of the thread.**\
> **The action is invalid since it's not the thread owner.**

This error occurs when SprintHub **is not the owner of the conversation (thread owner)** on Instagram. This usually happens in two scenarios:

#### 1. There is another application connected to Instagram/Facebook

If the account has integrations from **other chatbot/CRM systems**, Meta may assign another app as responsible for messages.

Normally, Facebook/Instagram gives priority to the **app installed first**, making it the owner of conversations. In this case, SprintHub cannot reply to messages until it is set as the main app.

#### 2. New Instagram/Facebook account

On newly configured accounts, even without other apps installed, it may be necessary to **manually set SprintHub as the default app for message handoff**, because Meta does not make this setting automatically.

### How to resolve

It is necessary to set SprintHub as **the default messaging app** in Meta.

#### Step by step

1. Go to the **Facebook/Meta Business** linked to Instagram.
2. Go to the settings of **Messages / Messaging** of Instagram or Facebook.
3. Locate the **Default app**, **Message handoff** or **Handover Protocol** (depending on the Meta interface).
4. Set the **SprintHub** as the primary app to receive and reply to messages.
5. Save the changes and do a new test on Instagram.

#### Warning

* If there are other apps installed, it may be necessary to **remove them temporarily** or reset SprintHub as the default.
* In **new accounts**, this setting may also be required, even without previous integrations.
* After the change, some conversations may need **a new message from the customer** to update thread ownership.

#### Important

This error is returned directly by the **Meta API (Facebook/Instagram)** and is related to **conversation ownership (thread owner)**, and is not an internal SprintHub error.
