+  Previously, the v1beta1 OpenTelemetryCollector CR's config field was incorrectly
+  marshalled, potentially causing issues when storing in etcd or retrieving via kubectl.
+  This fix ensures that the config is properly marshalled, maintaining the correct
+  structure and data types. For example, a config with nested maps and arrays will now
+  be correctly preserved when stored and retrieved, instead of being flattened or
+  losing structure.
