Such as the theme, after I call createOrReplaceInventoryItemGroup API, return a 500 error code, the body content is as follows：
{
"errors": [
{
"errorId": 25001,
"domain": "API_INVENTORY",
"subdomain": "Selling",
"category": "SYSTEM",
"message": "A system error has occurred."
}
]
}
However, I can see by calling the getInventoryltemGroup API that ltemGroup was created successfully, but variantSKUs has no content. But I made sure that when I created ltemGroup, I uploaded a valid sku. So the platform staff can see why the createOrReplaceInventoryItemGroup API system error？
