Magento 2 Add Custom attribute value on customer order graphql

• I have created two extensions and it’s an add fee on Order Total.
  Now on adding this fee to Get CustomerOrder Graphql so, we override the default Magento Get CustomerOrder Graphql and it’s working.
• But We Enabled both fee extensions and ran Graphql then only one fee show and not showing both extension fee on Get CustomerOrder Graphql.

Below is the Query.
query{
customerOrders {
items {
order_number
id
created_at
grand_total
status
fee1
fee2
}
}
}

when I execute the above query, it will display fee1 but it will not display fee2. If I disable the fee1 extension then fee2 displays on graphql.

Response:

{
“data”: {
“customerOrders”: {
“items”: [
{
“order_number”: “000000004”,
“id”: “4”,
“created_at”: “2023-12-05 11:58:52”,
“grand_total”: 146,
“status”: “pending”,
“fee1”: 5,
“fee2”: null,
}
]
}
}
}
