I just wanted to let you know I have moved your query here to our dedicated API forums.
As we’re not able to provide developer support ourselves, we have provided these forums that are moderated and responded to by our own developers and Partners.
I can see you’re already getting some input from the Community here, that’s really great to see!
This is the best place for any queries relating to the use of the Shopify API.
We are experiencing the same behavior and have seen it multiple times across multiple Shopify Stores. Also, on retry (same exact payload sent) it will succeed. We are also processing high volumes of transactions.
Same with us. It started about 2-3 weeks ago. Clearly, a Shopify issue and it would be amazing if you could get API support from Shopify, but it seems nonexistent.
Same error occurs for us, this results in a high volume of errors that must be manually resolved. It started on approx Feb. 15 and happens multiple times a day, seemingly at random.
As in the example above we are specifying a line item and quantity. On retrying with the same payload, the error does not recur, but unfortunately our system requires manual resolution for every occurrence. This is a major headache.
If the error message was correct (malformed line_items array) why do subsequent requests succeed? This is eating up hours every day for our support staff, and our customers are not happy
Does anybody by chance have an x-request-id from any of the problematic calls? You’d find this X-request-ID in the headers returned from the call that fails.
We’d recently deployed a fix to the /admin/orders/{order_id}/fulfillments.json endpoint to clean up the error reporting on POST’s to this endpoint, so if possible I’d like to confirm this issue is still ongoing with an x-request-ID from the past 14 days. Thank you.
Thanks @AU79 acknowledging receipt here. I tracked down the failing 400 request ID and the consequent 200 OK request ID for the same line item. Will respond once I have more information.
I’d just like to add that we have a fulfilment app and have started experiencing the same issue from 16 Feb 2022 and is still ongoing with 240 occurrences since then.
We are receiving the same error intermittently on fulfillments. Restarted the process it will run to success… Shopify do you have any updated on this…Looks like it has been almost 2 weeks since it was reported by Gman.
@Luke_K We now have 500+ recorded instances of this error, still occurring daily and causing failed shipment notifications, generating lots of unhappy emails and support tickets. I can understand the merchants’ frustration - from the customer’s perspective they are not aware their order has shipped, even though it has. If it would help to provide additional request IDs, I can provide those.
Any update you can provide would be greatly appreciated.
