"appSubscriptionTrialExtend" mutation internal error

[skoddowl]

Hello,

I'm trying to test "App Trial Extension" feature (https://shopify.dev/api/admin-graphql/unstable/mutations/appSubscriptionTrialExtend) from 'Unstable' version of Shopify API, but getting an error: "Internal error. Looks like something went wrong on our end. Request ID: b7ca7007-dcf1-4537-9b2f-6d0d142a7ec3 (include this in support requests)"

Here's example request I'm using:

mutation appSubscriptionTrialExtend($days: Int!, $id: ID!) {
  appSubscriptionTrialExtend(days: $days, id: $id) {
    userErrors {
      field
      message
    }
  }
}

Variables:
id = "gid://shopify/AppSubscription/<APP_SUBSCRIPTION_ID>"
days = 10

Request payload and variables looks OK, could you help with that? Thanks.

Hello, it seems to be a problem with something not implemented for test subscriptions.
