Strawberry Shake

Describe the bug

Hi!

Running through the "Subscriptions" tutorial and failing at step 3! The build step generates two errors:

The field onSessionScheduleddoes not exist on the typeSubscription``

For clarity, here's the type Subscription as found in schema.graphql:

type Subscription {
  onPriceChange(symbols: [String!]): AssetPrice!
  onNotification: NotificationUpdate!
}

Specs:

Blazor WASM, .NET 8.0
StrawberryShake.Blazor v13.7.0
StrawberryShake.Transport.WebSockets v13.7.0

Steps to reproduce

1. Complete the "Get started with Strawberry Shake and Blazor" tutorial (which I've made my own version of here)

2. Work through the Subscriptions tutorial steps 1 and 2, using Nuget package manager to download StrawberryShake.Transport.WebSockets

3. Run dotnet build

4. Get error log (if you're me, at least!)

Version

13.7.0

Start with the Strawberry Shake v13 Subscriptions tutorial, especially step 3, and compare its operation with the Subscription type shown in schema.graphql. Reproduce the problem with dotnet build using the listed Strawberry Shake 13.7.0 packages; done means the tutorial's documented steps and schema agree and the build completes without SS0002.
