Issue with EventBridge METAOBJECTS_CREATE Webhook

[SrBelmont]

I'm encountering an issue when trying to register an event on METAOBJECTS_CREATE using EventBridge. No matter what I try, I keep receiving the following error message:

"The specified filter is invalid, please ensure you specify the field(s) you wish to filter on."

Despite multiple attempts, the error persists. If anyone has successfully configured a filter for METAOBJECTS_CREATE on EventBridge, could you provide some guidance or examples?

Thanks in advance for any help or suggestions!

Apparently, you need to specify a filter to successfully register this webhook:

{
  "topic": "METAOBJECTS_CREATE",
  "webhookSubscription": {
    "arn": "your-address",
    "format": JSON,
    "filter": "type:packaging"
  }
}

How do you know what to filter for? I want to receive ANY metaobjects that are being created.

I tried to have following filter(s):

{
filter: "id:*"
}

{
filter: "name:*"
}

 This doesn't work and I have no idea what the filter is referencing.

Also why is the filter mandatory on this topic?
