+ * libp2p errors with extremely noisy errors here, which are deeply nested taking 30-50 lines.

+ * Error: Error occurred during XX handshake: Error occurred while verifying signed payload: Peer ID doesn't match libp2p public key
+ * ```
+ *
+ * Also the error's message is not properly formatted, where the error message is indented and includes the full stack
