Using Integromat to fetch Inventory Levels - Not working

[akabanov]

I am using Integromat to fetch inventory levels. It was working fine until 3 days later the Inventory API is returning 0 bundles. Nothing was changed as far as I know and my other store Inventory API calls are working just fine. 

Tried reinstalling the connection, but Shopify keeps returning 0 inventory. Please help!

Thank You,
