Hi @zhoud, that version of the TS SDK is not supported on beta-3, please could you try downgrading to v0.31.0, rerunning and reporting the result, thanks!

FetchError: request to http://127.0.0.1:4000/graphql failed, reason: connect ECONNREFUSED 127.0.0.1:4000

Are you still connecting to the beta-3 url, that looks like you are trying to connect to a local testnet?

5

yes，still connecting to the beta-3 url

6

Would you be able to share the repository? Or more of the code?

So I can see that the transfer() made on the beta-3 network is succeeding. However the FetchError is being thrown on line 22 by the getBalance() call on the receiver wallet.

By default, the provider url is set to http://127.0.0.1:4000/graphql. So when generating the destination wallet, it is using the default provider url. In order to connect the destination wallet to the beta-3 network, call:

await destinationWallet.provider.connect("https://beta-3.fuel.network/graphql");

before attempting to call getBalance() on the destination wallet, and you should be able to successfully log the receiver balance.

Alternatively, you could also pass the provider in when generating the destination wallet:

const destinationWallet = Wallet.generate({ provider });

Let me know if this doesn’t resolve it for you :slight_smile:
