If you are seeing the message 'Revise failed : The item specific Type is missing. Add Type to this listing, enter a valid value, and then try again.' please follow the instructions below to fix it.
eBay requires the item specific Type for this listing.
Add the "Type" specific for the listing in eBay, ensuring that the specific name matches exactly what eBay expects, i.e. "Type" and not "Types" or "Camera Type“.
Once you have done so you will be able to revise the item back to eBay via the dashboard.
