Hyperledger Fabric Error: 2 UNKNOWN: access denied: channel [mychannel] creator org [Org1MSP]

I'm trying to interact with the peers from JavaScript and I keep getting

I'm using the fabric-ca sample and I was able to execute transactions from cli and from cli through run-fabric.sh but I can't seem to do that from JS, I've created a new user and set the client and cert with client.setTlsClientCertAndKey(cert, key);, I even tried giving the admin cert and key from /data/orgs/org1/admin/msp/signcerts, /data/orgs/org1/admin/msp/admincerts and /data/orgs/org1/admin/msp/keystore as well as the ones from /data/tls/ but with no luck And this is the portion of the code I use:

var channel = this.client.newChannel('mychannel')

    let serverCert = fs.readFileSync('/data/org0-ca-chain.pem');

    channel.addOrderer(
        this.client.newOrderer(
            config.orderers['orderer1-org0'].url,
            {
                pem: Buffer.from(serverCert).toString()
            }
        )
    );

    serverCert = fs.readFileSync('/data/org1-ca-chain.pem');

    const peer1 = this.client.newPeer(
        config.peers['peer1-org1'].url,
        {
            pem: Buffer.from(serverCert).toString()
        }
    );
    channel.addPeer(peer1);
    this.eventhubs = []
    this.eventhubs.push(channel.newChannelEventHub(peer1));

    serverCert = fs.readFileSync('/data/org2-ca-chain.pem');

    const peer2 = this.client.newPeer(
        config.peers['peer1-org2'].url,
        {
            'pem': Buffer.from(serverCert).toString()
        }
    );
    channel.addPeer(peer2);
    this.eventhubs.push(channel.newChannelEventHub(peer2));
    this.channel = channel;
    console.log(this.channel)

    return this.channel.sendTransactionProposal(request);

Is there something wrong with my code or the way I do it? Can someone tell me what I am doing wrong? I've seen a few similar questions but those happened when composer was used mostly and I couldn't fix my problem with the answers from there,
