CORS

Hello, I’m trying to execute the code bellow:

config = {
      net: 'TestNet',
      script: Neon.create.script({
        scriptHash: 'de1a53be359e8be9f3d11627bcca40548a2d5bc1',
        operation: 'registerMailbox',
        args: [
          Neon.u.reverseHex(Neon.u.str2hexstring(neoWallet.getPublicKey(true))),
          Neon.u.reverseHex(Neon.u.str2hexstring('some string'))
        ]
      }),
      address: neoWallet.address,
      privateKey: neoWallet.privateKey,
      gas: 0
    };

    Neon.doInvoke(config).then(res => {
      console.log(res.response);
    });

And am getting errors like:

Request header field timeout is not allowed by Access-Control-Allow-Headers in preflight response.

Any idea?

sorry, there was some issue with publishing. It should be available now.

As for your question, there is no such type as Address for contract param. I guess that is where it went wrong. You should be using a bytearray to pass the address in. I would try Neon.sc.ContractParam.byteArray(neoWallet.address, 'address')

This issue occurs sporadically depending on the endpoint selected by neon-js. I’ve run into this as well. I haven’t dug into it, but I suspect it’s either an issue with specific endpoint versions, or with the server setup around that endpoint.
