Can I use an AWS Event-Bridge as my callback_url in my FulfillmentService?

[Todd_Trimakas]

As we'll be getting all our order notifications via this callback_url now, I'd like to move to EventBridge.

However, when trying to update the callback_url to my arn, I'm getting the following error:

ShopifyAPI::Errors::HttpResponseError ({"callback_url"=>["is invalid"]})
If you report this error, please include this id: b48ee742-7127-48c6-9edb-767849427fe4

I know my arn is right, because I'm using a similar one in production, BUT for a webhook and not inside my FulfillmentService.

For some details, my arn looks like this: 

"arn:aws:events:us-east-1::event-source/aws.partner/shopify.com/XXXXX/ship-dev"

So can we use EventBridge inside a FulfillmentService?
