Retriving Inventory returning nothing REST Api

[umsa-9649]

I'm attempting to retrieve all inventory items through the API. However, when I make a call to the endpoint "https://api.ebay.com/sell/inventory/v1/inventory_item," the response I receive contains the following data:

{ "total": 0, "size": 0 }

I've ensured that I've included all the required scopes during the consent acquisition process, and my access tokens are valid. Despite spending the last two days on this issue, I haven't been able to find a solution.

Were your items created by the Inventory API or by some other method? 

You may need to bulkMigrateListings to get them into the Inventory API format.

hi shipscript, thanks for replying. I created product by ebay default UI not through API I think this is bug of ebay that we are unable to see the listing which is not created through api it is nothing but a bad approach. Anyway I have shifted my system from REST API to Traditional API because when I try bulkMigrateListings is bad approach and is additional step
