Getting 404 error when adjusting inventory

[axsuul]

Hello,

We are getting the error when attempting to adjust inventory via this endpoint

PUT https://api.etsy.com/v3/application/listings/1607330511/inventory

404 {"error":"Could not find a listing with listing_id = 1607330511 and shop_id = 16662478"}

Is it something wrong with the listing itself? We've never seen this error before. Thanks!
