How to fix CSRF token error in sentry in asp.net core - asp.net-core

Question

I use Sentry to log errors in asp.net core 7, but errors not show in Sentry and I have this error in console log: CSRF Verification Failed A required security token was not found or was invalid. This is my code in program.cs:
public static IWebHost BuildWebHost(string[] args) =>
WebHost.CreateDefaultBuilder(args)
.UseStartup<Startup>()
.UseSentry(o =>
{
o.Dsn = #"http://876a08b927d4efcb98a769314452bbe#192.168.34.80:9000/8";
o.Debug = true;
})
.Build();
I test my code in .net 5 project and I can see logs in sentry panel.

A few things:
You said version 2.1.8 of the Sentry .NET SDK works. However, I don't recommend using that, as it's quite old (released Nov 21, 2020). We have fixed many issues and added many features since then.
You should read through the 2.x to 3.x migration guide.
From the DSN, it appears you are self-hosting the Sentry server. Versions 3.x of the Sentry .NET SDK requires Sentry version 20.6.0 or greater to work correctly. See docs here. The reason is that we now use Sentry's envelope endpoint. I suspect you are using an older version of Sentry.
Additionally, if using Sentry .NET 3.17.0 or greater, you'll either need Sentry 21.9.0 or greater, or will need to set options.SendClientReports = false. (See changelog notes.)
The CSRF failure has been discussed before with regard to using newer Sentry SDKs with older self-hosted Sentry servers.
You may also find that you need to update the configuration or architecture of your self-hosted Sentry server. See the documentation.
There have been other issues on this subject with Sentry self-hosted in the past. You may want to review them, or raise a new issue if necessary.
