The error message tells you what’s wrong, you mutation is using variables which you’re not using.

but the following ‘cartGiftCardCodesUpdate’ works !

mutation cartGiftCardCodesUpdate($cartId: ID!, $giftCardCodes: [String!]!) {
cartGiftCardCodesUpdate(cartId: $cartId, giftCardCodes: $giftCardCodes) {
cart {

Cart fields

}
userErrors {
field
message
}
warnings {

CartWarning fields

}
}
}

Please format your code using three back ticks: ` to help format/apply syntaxing.

mutation cartGiftCardCodesUpdate($cartId: ID!, $giftCardCodes: [String!]!) {
  cartGiftCardCodesUpdate(cartId: $cartId, giftCardCodes: $giftCardCodes) {
    cart {
      # Cart fields
    }
    userErrors {
      field
      message
    }
    warnings {
      # CartWarning fields
    }
  }
}

this is working but

`mutation cartGiftCardCodesAdd($cartId: ID!, $giftCardCodes: [String!]!) {
cartGiftCardCodesAdd(cartId: $cartId, giftCardCodes: $giftCardCodes) {
cart {

Cart fields

}
userErrors {
field
message
}
warnings {

CartWarning fields

}
}
}`

this is not, and both using same variables
`{
“cartId”: “gid://shopify//10079785100”,
“giftCardCodes”: [
“”
]
}`

You can confirm whether you are using the Storefront API or the GraphQL API, and also verify the request path.
