After a while, i found a document of yours about http request.

> **[HTTP configuration options | APM .NET Agent Reference \[1.12\] | Elastic](https://www.elastic.co/guide/en/apm/agent/dotnet/current/config-http.html#config-capture-body)**

in web.config my keys looks like this. Even though i added capturebody as equal all i still get same error. I would appreciate the help.
