Hello
Our user reported that certain line items in their orders count not be marked as fulfilled when using our app and had to manually change the fulfillment status on Shopify.
We got this “Failed to submit fulfill request.” error when looking into the log but were not able to find any description in the API docs.
We searched the community and failed to find any possible solutions and would really need some assistance from your end.
Here are 3 request ID for your reference:
