Pivot Runner null command

问题

While updating existing schema with PivotRunner on an existing database, I'm facing the error presented below.

I can't figure out why view may return an empty command. What are the most plausible cases ? If going over this error, I would have same error with a procedure, what should I check ?

Thanks for your answer,

The only trace I have in my log file is as below:

EDIT: These are the views elements of my pivot file

It looks like you have formatted the xml document. The definition of the view now starts with a new line and some spaces, and the pivot runner doesn't like it. There are 2 solutions:

Don't change the generated file (the easiest solution)
Use a custom pivot runner as provided below that trims the definitions

In this code we create a class that inherits from the PivotRunner and we change the definition of views, procedures and functions.

using CodeFluent.Runtime;
using CodeFluent.Runtime.Database.Management.SqlServer;
using System;
using System.Xml;

public class CustomPivotRunner : PivotRunner
{
    public CustomPivotRunner(string packageFilePath) : base(packageFilePath)
    {
    }

    protected override PivotRunnerProcedure NewProcedure(XmlElement element)
    {
        return new CustomPivotRunnerProcedure(this, element);
    }

    protected override PivotRunnerView NewView(XmlElement element)
    {
        return new CustomPivotRunnerView(this, element);
    }

    protected override PivotRunnerFunction NewFunction(XmlElement element)
    {
        return new CustomPivotRunnerFunction(this, element);
    }
}

public class CustomPivotRunnerProcedure : PivotRunnerProcedure
{
    public CustomPivotRunnerProcedure(PivotRunner runner, XmlElement element) : base(runner, element)
    {
        Definition = Definition?.Trim();
    }
}

public class CustomPivotRunnerFunction : PivotRunnerFunction
{
    public CustomPivotRunnerFunction(PivotRunner runner, XmlElement element) : base(runner, element)
    {
        Definition = Definition?.Trim();
    }
}

public class CustomPivotRunnerView : PivotRunnerView
{
    public CustomPivotRunnerView(PivotRunner runner, XmlElement element) : base(runner, element)
    {
        Definition = Definition?.Trim();
    }
}

class Program
{
    static void Main(string[] args)
    {
        var logger = new Logger();
        PivotRunner pivotRunner = new CustomPivotRunner(@"MyModelpivot.xml");
        pivotRunner.ConnectionString = CodeFluentContext.Get("Sample").Persistence.ConnectionString;
        pivotRunner.Logger = logger;
        pivotRunner.Action += PivotRunner_Action;
        pivotRunner.Run();
    }

    private static void PivotRunner_Action(object sender, PivotRunnerEventArgs e)
    {
        Console.WriteLine(e.Type + " " + e.Options);
    }

    public class Logger : IServiceHost
    {
        public void Log(object value)
        {
            Console.WriteLine(value);
        }
    }
}
