API Deprecation Notice from metafields API call to verify oauth

Hello!
I am getting the following warning in my logs even though my app is not using the deprecated API “metafields.valueType”.
I’m not sure where to find the code that causes this warning.
If you know anything about the same problem, please help me.

API Deprecation Notice: {
 message: 'https://shopify.dev/changelog/online-store-2-0-new-metafields-type-system-and-dynamic-sources',
 path: 'https://shop-name.myshopify.com/admin/api/2021-10/metafields.json?limit=1'
}

I clicked on “path” and got the following screen.

I see an object with the key “metafields” and an empty array for the value.
