ServiceStack Webhook + ServiceStack.Webhooks.OrmLite Subscription Store Plugin Issue

Question

I have enabled Webhook for my ServiceStack project in which I am using ServiceStack.Webhooks.OrmLite OrmLiteSubscriptionStore to store my subscription everything works fine except Delete operation, it gives below error:

    {
  "responseStatus": {
    "errorCode": "MissingMethodException",
    "message": "Method not found: 'Int32 ServiceStack.OrmLite.OrmLiteWriteExpressionsApi.Delete(System.Data.IDbConnection, System.Linq.Expressions.Expression`1<System.Func`2<!!0,Boolean>>)'.",
    "stackTrace": "[DeleteSubscription: 6/15/2020 12:42:28 PM]:\n[REQUEST: {id:c42c28e2-f432-40d1-b370-49a5a8506035}]\r\nSystem.MissingMethodException: Method not found: 'Int32 ServiceStack.OrmLite.OrmLiteWriteExpressionsApi.Delete(System.Data.IDbConnection, System.Linq.Expressions.Expression`1<System.Func`2<!!0,Boolean>>)'.\r\n   at ServiceStack.Webhooks.OrmLite.OrmLiteSubscriptionStore.Delete(String subscriptionId)\r\n   at ServiceStack.Webhooks.ServiceInterface.SubscriptionService.Delete(DeleteSubscription request)\r\n   at lambda_method(Closure , Object , Object )\r\n   at ServiceStack.Host.ServiceRunner`1.<ExecuteAsync>d__15.MoveNext() in C:\\BuildAgent\\work\\3481147c480f4a2f\\src\\ServiceStack\\Host\\ServiceRunner.cs:line 133\r\n",
    "errors": []
  }
}

Tried everything available publicly including version matching clearing local nuget cache nothing works for me.

Answer 1

You have a version mismatch with the version of ServiceStack you're trying to use vs the ServiceStack version that the ServiceStack.Webhooks.OrmLite NuGet package is built with.

You should raise an issue with the jezzsantos/ServiceStack.Webhooks GitHub project to release a new version that targets the latest v5.9.

Otherwise you will need to downgrade to use ServiceStack v5.5.0 that the NuGet package was built with.
