Error from ShipStation prevents using USPS Small Flat Rate Box I sent packages yesterday by USPS Priority Small Flat Rate Box without any problem.Today, I got this--I should also note that we have an Automation rule that sets Package to Small Flat Rate Box for all Priority shipments, as that is what we use most often. When I open a Waiting Order, the dimensions are seldom preset. That was the case with this order, so first time I got the message, I re-selected Priority Flat Rate and the dimension fields were filled. (Another bug that needs fixing, just not as critical.)But it still errored out, as you see here.I tried setting Service to a different carrier and Package to “Package”, then back to USPS/SFRB...no change.I was not able to solve it, so I repacked it in a USPS Small Mailing Package, changed ShipStation to “Package” and entered its dimensions, and was able to send it, albeit at higher cost.I need Small Flat Rate Box to work again, ASAP.
