80% inventory items are fetching but not 100%

[mamun3099]

I'm using the below api to retrieve all inventory items

GET https://api.ebay.com/sell/inventory/v1/inventory_item?limit=50&offset=50

But all the items are not fetching. It's like 80% items are fetching but not 100%. I've added 5 items today but these are not fetching also.

I've tried to check the item using sku but I've received the below error message. But the sku item is showing to eay dashboard listing page 

GET https://api.ebay.com/sell/inventory/v1/inventory_item/{sku}

errorId": 25710 

"domain": "API_INVENTORY"

"subdomain": "Selling"

"category": "REQUEST"

"message": "We didn't find the resource/entity you are requesting. Please verify the request"

Your call is set to skip the first 50 items and fetch the next 50 items.  Are you making multiple calls starting from zero?

Yes, I'm making multiple calls from zero to end
