Description

This exception only shows in production randomly. Blazor Webassembly app throws this exception randomly when an API request is made. Most of the time it works. Please check the stacktraces. All API call in browser is handled by the following method:

public abstract class BaseController
 {
     protected readonly string ControllerName;
     protected readonly string BaseLink = "api";
     protected readonly HttpClient http;

     public BaseController(string ControllerName, HttpClient client)
     {
         this.ControllerName = ControllerName;
         http = client;
     }

     protected async ValueTask<TRet> Request<TRet>(string actionName, object input)
     {
         JsonSerializerOptions options = new JsonSerializerOptions()
         {
             ReferenceHandler = System.Text.Json.Serialization.ReferenceHandler.IgnoreCycles,
         };
         HttpResponseMessage response = await http.PostAsJsonAsync($"{BaseLink}/{ControllerName}/{actionName}", input, options);
         response.EnsureSuccessStatusCode();

         var result = await response.Content.ReadFromJsonAsync<TRet>();
         return result;
     }

 }

Issue Details

Description

This exception only shows in production randomly. Blazor Webassembly app throws this exception randomly when an API request is made. Most of the time it works. Please check the stacktraces. All API call in browser is handled by the following method:

public abstract class BaseController
 {
     protected readonly string ControllerName;
     protected readonly string BaseLink = "api";
     protected readonly HttpClient http;

     public BaseController(string ControllerName, HttpClient client)
     {
         this.ControllerName = ControllerName;
         http = client;
     }

     protected async ValueTask<TRet> Request<TRet>(string actionName, object input)
     {
         JsonSerializerOptions options = new JsonSerializerOptions()
         {
             ReferenceHandler = System.Text.Json.Serialization.ReferenceHandler.IgnoreCycles,
         };
         HttpResponseMessage response = await http.PostAsJsonAsync($"{BaseLink}/{ControllerName}/{actionName}", input, options);
         response.EnsureSuccessStatusCode();

         var result = await response.Content.ReadFromJsonAsync<TRet>();
         return result;
     }

 }

Reproduction Steps

I have not been able to reproduce this problem in development environment. Stacktrace should provide some clue.

Expected behavior

Code should work without InvalidCastException

Regression?

It works in .net 6. It also works in .net 7 most of the time.

Known Workarounds

Reloading the page solves the problem.

We would need a minimal repro in order to take a better look at this, unfortunately.

Same thing here, I have struggled with this for a week now 😕It happens randomly but only if I publish a release build with these parameters: --configuration "Release" --runtime win-x64 --self-contained
It started about the same time as I upgraded to latest .NET. I have tried a million different JsonSerializerOptions without result.

Code:
` T t = JsonSerializer.Deserialize(json,
new JsonSerializerOptions()
{
PropertyNameCaseInsensitive = true,
DefaultIgnoreCondition = System.Text.Json.Serialization.JsonIgnoreCondition.WhenWritingNull,
IgnoreReadOnlyProperties = true,
});

catch (InvalidCastException e)
{
Console.WriteLine($"{url} {e.Message} {json}");
}
`

output in browser:
(my url) Arg_InvalidCastException (valid json checked with several different validators)

@UserIsAmitHasan or @wafn007, would it be possible to share a standalone project that demonstrates the issue? A zip file or a repo containing a Blazor project, including the inputs that are triggering the failure.

I think I have a fix for my issue or at least a work around. The problem is the construction of the JsonSerializerOptions which seems to be a bit strange. Using a static JsonSerializerOptions everything works as expected, no errors yet at least. I found below link suggesting using a single instance of the options object between calls for performance reasons. Maybe something strange is happening inside the framework classes since they cannot cope with a slow options construction??
https://learn.microsoft.com/en-us/dotnet/standard/serialization/system-text-json/configure-options?pivots=dotnet-7-0

    private static readonly JsonSerializerOptions deserializerOptions = new()
    {
        PropertyNameCaseInsensitive = true,
        DefaultIgnoreCondition = System.Text.Json.Serialization.JsonIgnoreCondition.WhenWritingNull,
        IgnoreReadOnlyProperties = true,
    };

    T t = JsonSerializer.Deserialize<T>(json, deserializerOptions);

eiriktsarpalis · 2022-12-12T12:22:41Z

We would need a bit more information, including the type of T and the json payload used when deserializing.

UserIsAmitHasan · 2022-12-12T12:42:45Z

@eiriktsarpalis T is a class and the problem happens at property getters of type string.

Here : CustomSerialNo is a property of type string
System.InvalidCastException: Arg_InvalidCastException
at System.Object.CustomSerialNoGetter(Object )

Here : Guid is a property of type string
System.InvalidCastException: Arg_InvalidCastException
at System.Object.GuidGetter(Object )

I had to go back to .net 6 to make the app reliable.

eiriktsarpalis · 2022-12-12T12:57:32Z

In order for us to take a closer look, please share a minimal, self-contained project that demonstrates the issue.

@eiriktsarpalis thanks for your quick reply. Issue is tricky and occurs randomly. Let me try to produce a minimum repo. I will get back to you when done; may take a couple of days due to the nature of the problem. Thanks again.
