+    Reth uses the Zepter CLI to detect abnormalities in Cargo features, e.g. missing propagation.
+
+    It looks like one more more checks failed; please check the console output.
+
+    You can try to automatically address them by installing zepter (`cargo install zepter --locked`) and simply running `zepter` in the workspace root.
