🐛 Bug Report: querry does not work on Ios but does work on windows and android when using c#

[StefanLaumann]

👟 Reproduction steps

When I run this code on a IPhone:

 result = await databases.ListDocuments(AWConst.DatabaseKey, AWConst.ActivityModelTableId,
     [
         Query.Equal("ukey", activity.Ukey)
     ]);

👍 Expected behavior

It should give me a result with one document.

👎 Actual Behavior

It actually give me an Execption, saying Syntax Error in the querry.
But on Windows and Android it works fine.

🎲 Appwrite version

Appwrite Cloud

💻 Operating system

Something else

🧱 Your Environment

I use the .net sdk from nuget in Version 0.8.1

👀 Have you spent some time to check if this issue has been raised before?

• I checked and didn't find similar issue

This is the querry string, that is created by the querry class:
{"method":"equal","attribute":"ukey","values":["f3e70104-a0dc-4bf9-9c30-dca03a69e53d"]}

It is the same on all plattforms.
I checked again: On a Windows machine, Android did work in a Emulator.
Windows is working.
Ios on a attached IPhone is not working.
Building on a Mac does also not help. Ios is not running, and always giving this exception with the Syntax error in the querry.
But when I try without a querry, the code runs fine even on Ios.
For example, this works fine:
result = await databases.ListDocuments(AWConst.DatabaseKey, AWConst.ActivityModelTableId);

@StefanLaumann, thanks for creating this issue! Would you please share the exact error message you're getting? Would you please also share your project id?

@adityaoberai, any idea why this is happening?

@StefanLaumann when you say that you're running the code on Windows, Android, and iOS, what exactly are you doing? Are you using a framework like .NET MAUI or something else?

Also, can you share the entire error message as well as info about your IDE (for both Windows and Mac)? This will help provide us with more context that can help us debug this issue.

Here is a message string:

Invalid query: Syntax error
Appwrite
   at Appwrite.Client.<Call>d__31`1[[Appwrite.Models.DocumentList, Appwrite, Version=0.8.1.0, Culture=neutral, PublicKeyToken=null]].MoveNext()
   at Evento.Data.AppWriteDatabase.CreateActivity(ActivityModel activity) in C:\Users\Stefan\Documents\Projekte\Condivido\Evento\Evento\Data\AppWriteDatabase.cs:line 48
-2146233088
System.Collections.ListDictionaryInternal

That comes from this code:

            List<string> querries = new List<string>();
            querries.Add(Query.Equal("ukey", activity.Ukey));

            DocumentList? result;
            try
            {
                result = await databases.ListDocuments(AWConst.DatabaseKey, AWConst.ActivityModelTableId, querries) ;
            }
            catch (Exception exi)
            {
                var message = exi.Message;
                message += "\n" + exi.Source;
                message += "\n" + exi.StackTrace;
                message += "\n" + exi.HResult;
                message += "\n" + exi.Data;
                Debug.WriteLine(message);
                result = null;
            }

The whole project is a .Net Maui App in .Net 8.
I am using a Desktop Computer with Win 11 and this IDE:
Microsoft Visual Studio Community 2022 (64-Bit) - Current
Version 17.9.6
From here, I can compile the code for Windows, Android and IOS.
Also, I have a Macbook. There I am using VS Code 1.89.1 and the latest MacOS,
but compile only IOS.

The Project ID: 66486edc002f6b4e5592
Listing the documents without a querry works on all plattforms. Also creating a document.
Listing the documents with querry worked on Windows (App compiled for Windows ) and on the Android Simulator, but not on the connected IPhone...

[StefanLaumann]

I created a new project on AppWrite and a new repository to test this.
Since the repro also contains all the keys, I will delete it in some time again,
but for now, this can be used for testing:

@StefanLaumann This looks like a bug in MAUI, I've opened an issue here: xamarin/xamarin-macios#20629

There is a workaround though, you can add this block to your .csproj file:

	<PropertyGroup Condition="$(TargetFramework.Contains('-ios')) == true OR $(TargetFramework.Contains('-mac')) == true">
		<UseNativeHttpHandler>false</UseNativeHttpHandler>
	</PropertyGroup>

@abnegate @adityaoberai @stnguyen90
I have to thank you all for the quick response and the nice workaround.
This did the job :-)
Kind regards
