Creating a Forum Topic In Telegram Super Group isn't working

Hey all,

I try to create a Forum Topic in a Telegram Super Group using the Telegram API. However, I keep getting the same error:
[400] Bad Request: title must be non-empty

The problem is: I give a title in the API call that is not empty. So I am not sure how I can fix this.

Here is a quick video explaining the issue: ClickUp

Documentation on the API call:

Input bundles:

**[
    {
        "qs": [],
        "body": "{\n\"channel\":\"-1002596210851\",\n\"title\":\"Test!\",\n\"chat_id\":\"-1002596210851\"\n}",
        "method": "POST",
        "headers": [
            {
                "key": "Content-Type",
                "value": "application/json"
            }
        ],
        "bodyType": "mapped_body",
        "urlMethod": "createForumTopic"
    }
]**

Output bundles:

[
    null
]

Any help is greatly appreciated!

Kind Regards,

Joren
