+
+Ignore these Hanami errors by default:
+
+- Hanami::Router::NotAllowedError (for example: sending a GET request to POST endpoint)
+- Hanami::Router::NotFoundError
+
+They are usually errors you don't want to be notified about, so we ignore them by default now.
+
+Customize the `ignore_errors` config option to continue receiving these errors.

+Read the Hanami Action name without metaprogramming in Hanami 2.2 and newer. This makes our instrumentation more stable whenever something changes in future Hanami releases.
