Issue

Some users in Distru have not had their transfers cache updated since 06/28/2022. An example of this is this Asana ticket.

Data

Impersonate user: yaya+1@flavrhouse.com Order ID not syncing: 495908

Investigation

I tried tried to run a transfer update job in our production env for the license during the date of 06/28/2022 like so while having a bunch of logs in place in lib/distru/metrc/transfer/transfer.ex:

license = Distru.Repo.get!(Distru.License, 235592) |> Distru.Repo.preload(:company);

Distru.Metrc.Transfer.update_transfer_cache(
    license,
    license.company.metrc_default_user_key,
    Timex.shift(Timex.now(), hours: -23),
    Timex.now()
)

I found that we failed to update Order ID 495151 that crashed the transfer cache update. It turns out that the order had a line item which did not have a package associated, even though it was already matched to Metrc transfer with metrc_id=3680314.

I then checked the payload from Metrc on that transfer and noticed some oddities:

Transfer payload

  1. ReceivedPackageCount=19, ReceivedDeliveryCount=1

Transfer Deliveries Payload

  1. ActualArrivalDateTime=null, ReceivedDateTime=2022-06-28T20:50:37+00:00, DeliveryReceivedPackageCount=19

Transfer Packages Payload

  1. Every single package in here had ShipmentPackageState=Accepted

Conclusion

So it seems that the Metrc transfer 3680314 was received on 2022-06-28T20:50:37+00:00, and we tried to update the SO 495151, one of it's line items (id: 5759686) had no packages associated to it, causing our update job to crash.

UPDATE: The customer said that the specific line item where the package was removed (id: 5759686) from had it's received quantity be 10 instead of 11. However, this still doesn't explain how the package was removed from the line item

UPDATE #2: I checked further and it seems that the package has a transaction history item of being associated with the SO, and it even has a selling stock, but that stock does not have an order_item_id associated, however the stock does have an assembly_output_item_id associated:

-[ RECORD 5 ]-----------+------------------------------

teardown_output_id      |
harvest_id              |
breakdown_input_id      |
breakdown_output_id     |

The assembly associated to the output item is Assembly ID: 2053051 which is a inline_repackage assembly.

UPDATE #3: In the meantime to fix the issue for the customer, I re-attached the selling stock to the order item, and reattached the package to the order item like so:

UPDATE stocks SET order_item_id = 5759686 WHERE id = 12172533;
UPDATE order_items SET package_id = 2565018 WHERE id = 5759686;

UPDATE #4: Apparently the transactions associated with the package also show 2 transactions of this package being added to the SO, but zero transactions of it being removed from the SO, and also neither transactions have the order_item_id filled
