So I did what he did and it fixed my error too. I'm pretty certain I have an English locale. Although its possible the generate item cache wasn't necessary. I was able to attempt a post of my item before it finished generating.
What generate item cache does is create a copy of the static database with the item names replaced by the ones retrieved through your client and then stores it in your savedvariables. If your client is english it will simply create an exact copy and then increase your loading time/memory usage for no reason.
The problem you had I assume was that you had needlessly generated a database at some point and then the static database format changed but the copy in your savedvariables didn't change so it didn't match what aux was expecting anymore.
Bottom line: If you don't have a non english locale then don't use generate item cache, it will slow down the performance, may require regeneration on version updates and won't have any benefits whatsoever.
