Not a bug, just make sure that mutation is defined correctly:

mutation appSubscriptionCreate($test: Boolean, $trialDays: Int, $lineItems: [AppSubscriptionLineItemInput!]!, $name: String!, $returnUrl: URL!) {
  appSubscriptionCreate(test: $test, trialDays: $trialDays, lineItems: $lineItems, name: $name, returnUrl: $returnUrl) {
    appSubscription {
      id
      name
      test
      trialDays
      returnUrl
    }
    confirmationUrl
    userErrors {
      field
      message
    }
  }
}

{
  "lineItems": {
    "plan": {
      "appRecurringPricingDetails": {
        "discount": {
          "durationLimitInIntervals": 3,
          "value": {
            "amount": 3.00
          }
        },
        "interval": "EVERY_30_DAYS",
        "price": {
          "amount": 9.00,
          "currencyCode": "USD"
        }
      }
    }
  },
