I've recently been receiving an error with an error code of 10007 and an error message stating "Internal error to the application." when doing a GetSellerList request to the Trading API in the sandbox environment. I was previously able to make GetSellerList calls successfully, but now I'm receiving this error out of the blue. From the research that I've done, I've deduced that this is just a random issue on eBay's side or there is some data in one of more of my listings that is causing this issue to occur.
I went so far as to remove every single one of my listings and I still receive the error. I really need to get this working in order to validate my integration code. Please advise on what steps I need to take to resolve this issue. Below is the XML request that I'm making and the response I get back:
<?xml version='1.0' encoding='utf-8'?>
<?xml version="1.0" encoding="UTF-8"?>
<ShortMessage>Internal error to the application.</ShortMessage>
<LongMessage>Internal error to the application.</LongMessage>
