[Urgent] FinalUrls is READONLY

[ullfindsmit]

Describe the bug:
FinalURLs is now readonly so I removed the line and now I get an error when trying to create a new Ad.

In the latest library the FinalUrls property is READONLY
Assembly Google.Ads.GoogleAds, Version=10.2.0.0, Culture=neutral, PublicKeyToken=52807268f2b614dc

However, in the earlier version it was NOT readonly.
Assembly Google.Ads.GoogleAds, Version=10.1.0.0, Culture=neutral, PublicKeyToken=52807268f2b614dc

What is the new way to set the FinalURLs value?

Steps to Reproduce:

                    // Create the ad group ad object.
                    AdGroupAd adGroupAd = new AdGroupAd
                    {
                        AdGroup = oAdGroup,
                        // Optional: Set the status.
                        Status = AdGroupAdStatus.Paused,
                        Ad = new Ad
                        {
                            **FinalUrls = { oAdGroupAd.FinalUrls },**
                            ExpandedTextAd = new ExpandedTextAdInfo
                            {
                                Description = CSVParameterObj.Description,
                                Description2 = CSVParameterObj.Description2,
                                HeadlinePart1 = CSVParameterObj.HeadlinePart1,
                                HeadlinePart2 = CSVParameterObj.HeadlinePart2,
                                HeadlinePart3 = CSVParameterObj.HeadlinePart3,
                                Path1 = CSVParameterObj.Path1,
                                Path2 = CSVParameterObj.Path2
                            }
                        }
                    };

Expected behavior:
Backward compatibility or documentation on how to fix.

Hi,

Thanks for opening the issue here. The error you received looks to be due to there being zero final URLs on the ad sent in the request. Does the ad you're copying from (oAdGroupAd) have a non-empty FinalUrls collection?

Thanks

[ullfindsmit]

Yes, the property FinalUrls collection is blank.
The reason it is blank is because the property FinalURLs used to be read/write in 10.1 and is readonly in 10.2
There is no documentation as to HOW to set the value in 10.2.

I am hitting this issue as well with setting the FinalURls property on the AdGroupCriterion object. It is read only in both versions 9 and 10.2 which I just upgraded to.

ullfindsmit is right.
In Version 10.1 its allow to set value of finalURLs Please check this

There seems to be multiple issues being discussed on this thread, so let me go over them one by one.

1. In C#, repeated fields are treated as readonly lists. So this code should work:

private void TryArrayInitialize()
{
  Ad oAdGroupAd = new Ad();
  string oAdGroup = "";
  AdGroupAd adGroupAd = new AdGroupAd
  {
    AdGroup = oAdGroup,
    // Optional: Set the status.
    Status = AdGroupAdStatus.Paused,
    Ad = new Ad
    {
      FinalUrls = { oAdGroupAd.FinalUrls },
      ExpandedTextAd = new ExpandedTextAdInfo
      {
      }
    }
  };
}

The relevant C# feature is discussed here: https://docs.microsoft.com/en-us/dotnet/csharp/programming-guide/classes-and-structs/object-and-collection-initializers#object-initializers-with-collection-read-only-property-initialization

2. The question is why this code stopped working between 10.1 and 10.2. I don't have a good answer to that, because the code hasn't changed between 10.1 and 10.2. So I can't replicate this issue, even though I also don't doubt this might be affecting some users because @friedenberg also ran into this issue once. For reference, here are the files.

google-ads-dotnet/src/V8/Types/Ad.g.cs

Lines 301 to 303 in 86eefe5

	public pbc::RepeatedField<string> FinalUrls {
	get { return finalUrls_; }
	}

google-ads-dotnet/src/V8/Types/Ad.g.cs

Lines 290 to 293 in 127ae51

	public pbc::RepeatedField<string> FinalUrls {
	get { return finalUrls_; }
	}

Can someone provide a minimal project that helps replicate this issue?

I am using

Microsoft Visual Studio Community 2019
Version 16.11.6
VisualStudio.16.Release/16.11.6+31829.152
Microsoft .NET Framework
Version 4.8.04084

And for command line:

SDK Version: 5.0.404

And OS version:

Windows 10, Microsoft Windows Version 20H2 (OS Build 19042.1415)

The following projects compile fine locally.

@AnashOommen thank you for staying on this issue. The issue is that the FinalURLs property is ReadOnly in 10.2.0.0 and I am not able to set its value as you suggested FinalUrls = { oAdGroupAd.FinalUrls }

[AnashOommen]

@ullfindsmit can you please attach a minimal project that illustrates the issue? Or otherwise, confirm if you can compile the attached Compilation Issues.zip?

[ullfindsmit]

I was finally able to get it to work. The solution was to not use the inline declaration but instead to create a new Ad object Then instead of assigning the final urls, simply using oAd.FinalURLs.Add("string")
