Internal error. Looks like something went wrong on our end when request to use fulfillmentCreateV2

  "errors": [
    {

    }
  ]
}

Anyone can help me to fix it?

I have the same problem with a simple "mutation" like this:

mutation {
	Order1: fulfillmentCreateV2(
		fulfillment: {
			notifyCustomer: true,
			trackingInfo: { 
				number: "123456789"  company: "USPS",  url: "http://www.google.com" 
			}
			lineItemsByFulfillmentOrder: { fulfillmentOrderId: "gid://shopify/FulfillmentOrder/2058876747821",  fulfillmentOrderLineItems: [] }
		}
	) 
	{
		fulfillment{ trackingInfo{ url number company } createdAt id }
		userErrors { field message }
	}
}

Error:

[message] => Internal error. Looks like something went wrong on our end.

@Yu727 ,

You ran into this error because you are trying to create a fulfilment for FulfillmentOrder ID 2036838105184, but that Fulfillment Order ID does not exist on the store ul*******on.myshopify.com

Why can't we get better error messages that tell us what the issue is, rather than having to post here to figure out what the issue is?
