I ran across something that my be a useful piece of information. When I run these queries (in the case of the last set of code 22 responses, the packs_per_day query) I’ve been using the date_from criteria (set to the last day or two) and using first:1 to get the first record. Those are the ones where I often get the code 22 errors. But I found that if I specify an order number in the criteria, not only does it seem to work every time, but it seems to come back much faster. Querying without an order number, even when returning a single record, will sometimes take 45 seconds or so when it doesn’t return an error. Specifying an order number takes a second or less to get the same record.
Unfortunately, I cannot specify orders for every packing record I need to pull, but seeing your response in this other thread about the possibility of nonexistent SKUs made me think something like that may be going on.
Thanks,
Jeremy
