Instantiating CreateLibp2p function with Proper Assessment to PeerIds

[peterkim2014]

Current Method

1. Made a peerId using the createEd25519PeerId.
   const peerId = await createEd25519PeerId({ privateKey: privateKey });

2. Store into json, which eliminates the formats of ed25519, converts the values into string.

3. Retrieving the data of peerId to instantiate the CreateLibp2p.

---

Process

• When I store the data as hex values, because Uint8Array doesn't store the format, only the values, I'm trying to revert the hex values into a Uint8Array to extract the same peerId using the public and private key.

Error

• CreateLibp2p doesn't instantiate the node. Instead, I'm given these error messages: if (publicKey.length === MARSHALLED_ED225519_PUBLIC_KEY_LENGTH) {
  ^

TypeError: Cannot read properties of undefined (reading 'length')

The pasted details below is the data structure of the peer.meta that I'm using, in order to retrieve the peerId.

• Before inputting the meta into createFromPrivKey function, I'm converting the hex values into Uint8Array

const peerIdForm = await createFromPrivKey(peer.meta);
