Creating a fulfillment gives 'Line Item {{LINE ITEM ID}} does not exist' but the line item exists'

[Andrew-Corknine]

Hello,

When using API version 2020-04 and creating a fulfillment I am getting a strange error on some orders.

The error states

Line Item {{LINE ITEM ID}} does not exist' but the line item exists

when passing a line item ID that does exist on the order.  This has only started happening recently.  Is there anyway to get a fix for this?

Hi @Andrew-Corknine ,

Could you provide the value of the X-Request-ID header from the Shopify API error response? With this response header we can go through our platform logs and see exactly why this error happened. If you are unable to provide this, please provide information about the Shop, Line Item ID, and query that is causing these errors.

Hi @hassain,

Hey @Andrew-Corknine,

We checked the logs for this one and I believe I can see what's happening. The line_item returning an error was assigned to a fulfillment_service at the time the order was created, but has since been switched to have inventory managed by Shopify. Your API call is attempting to fulfill the item through the fulfillment_service, but the call is failing since the item is no longer assigned to that service.

To be honest I'm not 100% sure how the API is supposed to respond when the fulfillment_service has been modified after an order is placed, so I'm going to raise this with our developers for clarification. In the meantime, you can try temporarily re-assigning that variant to the fulfillment service and attempt the fulfillment again. I'll post here with an update when I get word back from our developers.

Hi @_JB 

That seems strange.  I am not really seeing that.  For example on request id 

787bf853-3312-47c6-93b7-952681ebb8da

The fulfillment service on the line_item and currently on the variant are both set the the fulfillment service I am trying to create the fulfillment for.  Am I missing something?

Hey @Andrew-Corknine,

This request looks different, and the call looks to have been made correctly so I'm not sure where the error is coming from. I'm going to move this to DM so I can get some more details from you. If anyone else reading along is having a similar problem, please let me know here.

Hi,

I've got the same issue,

I've got all the details that match fulfillment_order, but it still doesn't want to fulfill it

not sure what to do next?

Fulfilment looks like this:

{
"fulfillment": {
"message": null,
"location_id": "35193421885",
"notify_customer": true,
"tracking_info": {
"number": "[tracking]",
"company": "Royal Mail",
"url": "https://www.royalmail.com/track-your-item/?trackNumber=[tracking]"
},
"line_items_by_fulfillment_order": [
{
"fulfillment_order_id": "6117640831037",
"fulfillment_order_line_items": [
{
"id": "12213748629565",
"quantity": 3
},
{
"id": "12213748662333",
"quantity": 3
}
]
}
]
}
}
