Hi,

Getting following error in HttpPatch
"The JSON value could not be converted to Microsoft.AspNetCore.JsonPatch.JsonPatchDocument"

I have created an application and using following code but debug is not being focused on
[HttpPatch]
public IActionResult Patch([FromBody] JsonPatchDocument<weatherforecast> patch)
{

return Ok();
}

What I have tried:

Install-Package Microsoft.AspNetCore.Mvc.NewtonsoftJson -Version 3.1.6

Seems adding custom converters should solve it.

Reference: JsonPatchDocument Error The JSON value could not be converted to Microsoft.AspNetCore.JsonPatch.JsonPatchDocument · Issue #13938 · dotnet/aspnetcore · GitHub[^]

You'll need to update your application to reference Microsoft.AspNetCore.Mvc.Newtonsoft.Json package:

1. Install the Microsoft.AspNetCore.Mvc.NewtonsoftJson NuGet package.
2. Update the project's Startup.ConfigureServices method to include a call to AddRazorRuntimeCompilation:

services
        .AddControllersWithViews()
        .AddNewtonsoftJson();

Another similar report and solve: PatchRequest fails with error The JSON value could not be converted to Microsoft.AspNetCore.JsonPatch.JsonPatchDocument · Issue #22620 · dotnet/aspnetcore · GitHub[^]
