Trying to migrate one item using my own code, returned Error Code 2003:

payload = {"requests" : [{ "listingId": "253937175716" }]}

RlogId: t6pitnmsgwj70%3D9iptpitnmsgwj70*1357501%29pqtfwpu%29osu%29fgg%7E-fij-1670380c682-0x552f9

Then I tried using the API EXPLORER. It complained of NO ITEM until I used the legacy ItemID as shown in the UI listing. ( I thought we were supposed to use the new method v1|ITEM_ID|0 etc.)

payload = {"requests" : [{ "listingId": "253937175716" }]}

rlogid:t6pitnmsgwj70%3D9un%7Fpitnmsgwj70*1223636%29pqtfwpu%29sm%7E%29fgg%7E-fij-16703b4a728-0x21476

This result was error 2500

I made sure that my listing conforms to all requirements to migrate. Token seems to be OK as I got past the authentication errors. Seems to find the item as I got past the ITEM NOT FOUND errors.

I notice that I am now unable to edit my listing using the web UI, does this mean that it worked?
