2.0@beta error TypeError: Right-hand side of 'instanceof' is not an object

[dangell7]

I'm not exactly sure what has changed as the docs are still in PR, but when I try client.connect() in a web pack application I get the following error:

TypeError: Right-hand side of 'instanceof' is not an object

if I leave out connect, then I get a NotConnectedError error.

Any ideas?

Hi @dangell7. Thanks for trying out the beta and for opening an issue.

Could you give us a little more information regarding the environment you're using xrpl.js in and/or a code snippet to help us reproduce the issue?

Thanks again! Nathan

getXrpl.js using ripple-lib

import { RippleAPI } from 'ripple-lib';

const getRippleSession = new Promise(((resolve, reject) => {
    let results;
    const url = process.env.XRP_NETWORK_URL;
    const api = new RippleAPI({
      server: url
    });
    api.on('error', (errorCode, errorMessage) => {
      reject(errorMessage);
      return;
    });
    api.on('connected', () => {
      results = {
          api,
      };
      resolve(results);
      return;
    });
    api.on('disconnected', (code) => {
      // code - [close code](https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent) sent by the server
      // will be 1000 if this was normal closure
      console.warn('disconnected, code:', code);
      return;
    });

    api.connect().then(() => {
        results = {
            api,
        };
        resolve(results);
        return;
    }).catch((error) => {
      reject(error);
    });
}));

export default getRippleSession;

The above code works.

getXrpl using xrpl:

import { Client } from 'xrpl';

const getRippleSession = new Promise(((resolve, reject) => {
    let results;
    const url = process.env.XRP_NETWORK_URL;
    const api = new Client(url);
    api.on('error', (errorCode, errorMessage) => {
      reject(errorMessage);
      return;
    });
    api.on('connected', () => {
      results = {
          api,
      };
      resolve(results);
      return;
    });
    api.on('disconnected', (code) => {
      // code - [close code](https://developer.mozilla.org/en-US/docs/Web/API/CloseEvent) sent by the server
      // will be 1000 if this was normal closure
      console.warn('disconnected, code:', code);
      return;
    });

    api.connect().then(() => {
        results = {
            api,
        };
        resolve(results);
        return;
    }).catch((error) => {
      reject(error);
    });
}));

export default getRippleSession;

Notice the resolve fallbacks. net, tls and fs were added for xrpl js.

So if I change the RippleAPI to Client directly without changing anything else I get:

ValidationError: server URI must start withwss://,ws://,wss+unix://, orws+unix://.

The url is wss://s.altnet.rippletest.net:51233 so that error isn't clear.

Then if I change the Client to Client(url) instead of Client({ server: url }) I get the error that created the issue.

Is this error from using React, or through regular webpacked code?

[natenichols]

@dangell7 Thank you so much for opening an issue, and providing a lot of relevant information about the issue.

I was able to reproduce the issue locally, and should have a fix.

It looks like the fix is the same as the fix for another issue we saw with react this morning. We have this fix up in PR at #1694.

We'll post in this thread when we publish a beta.4 with this fix in it.

Thanks again, Nathan

[dangell7]

You guys ROCK!!

[natenichols]

2.0.0-beta.4 has been published. It appears to resolve this issue on my machine.

Let us know if this works for you when you get a chance to try it out.

[dangell7]

WOW. What a turn around time.. All good here.. Popping a few errors. I'll post them here but no need to keep this open as the new docs likely already point to the new functions.

[dangell7]

Here is the list of functions I am missing..

getAccountInfo getAccountObjects

deriveAddress existed on both keypairs and the api. Now only keypairs. Probably not an issue for most.

@natenichols I read your review comment about balances vs account_info. I have a feeling I will end up using balances more than account info. I can also tell you that this is because I now use currencies more that the native XRP token. So I would assume new developers will gravitate to account_info and later transition to balances when they have a multi currency use case.

[dangell7]

result.api.sign not a function. Probably more me making deprecated calls but this info might be useful for others.

[mvadari]

We're still working on the full migration docs, but here's a draft of that: https://github.com/XRPLF/xrpl-dev-portal/blob/xrpljs2.0/content/references/xrpljs2-migration-guide.md

[JST5000]

@dangell7 I'm on the team with @mvadari and @natenichols and I'm doing interviews to see what migration problems folks run into. If you're interested, we can migrate some code together 🙂 (Just send me an email at jmills@ripple.com and we can sort out a time) - If you don't want to, no pressure though!

[dangell7]

So just to update we had a meeting today that went really well. I have updated my code base.

getAccountInfo getAccountObjects

Were simple and I do like how the ws/rpc call parameters are what is put into the request function on the client. It forces developers to have a general understanding of the api without just calling functions willy nilly.

prepareTx signTx submitTx

These were a little different.

return api.sign(tx, seed)

became

const wallet = Wallet(seed);
const signedTx  = wallet.signTransaction(tx);
tx.signedTransaction = signedTx;
return tx;

A few things to note here is that prepareTransaction using the client, doesn't return an object with an included txJSON object, it returns the final json transaction.

I can elaborate. Before prepareTransaction would return something like {txJSON: {new tx stuff}, tx: {old tx stuff}} where now it returns the "autofilled" tx. Just a minor change. Instead of sign(tx.txJSON) it became signTransaction(tx).

Another is that wallet.signTransaction doesn't return the full transaction but the signedTransaction.

Finally submitTransaction just returned a different kind of result but no issues with that. Still got all the info I need. I also like the outside parameters if I dont care about the result data.

Thanks again for your time.

In case somebody here has the same problem with xrpl.js and SvelteKit (or other Vite-powered FE): Vite seems to ignore the browser field for ws and just tries to use ws instead of native browser websocket API, which throws an error.

https://github.com/XRPLF/xrpl.js/blob/main/packages/xrpl/package.json#L20-L22

A workaround of putting an alias for it manually works (in your vite.config.js):

resolve: {
        alias: {
            // your other aliases
                        // ...
            ws: './node_modules/xrpl/dist/npm/client/WSWrapper.js'
        }
    },

Vite's repo is aware of that https://github.com/vitejs/vite/issues/7576#issuecomment-1202074349
