+### Normalize "operation_name" value inside supergraph request ([Issue #5014](https://github.com/apollographql/router/issues/5014))
+
+At present, the behavior of `request.body.operation_name` in Rhai scripts is such that it is a direct copy of `operationName` from the client request.
+So `request.body.operation_name` can be empty even if `query` contains a named query. For example:
+```json
+{
+  "query": "query OperationName { me { id } }"
+}
+```
+In this case, `request.body.operation_name` was empty because the client didn't specify `operationName.`
+
+This behavior is very confusing to users who expect it to have an operation name if `query` contains a named query.
+After this change, `request.body.operation_name` will always default to the operation name extracted from parsed `query`.
