I try to link address (new) to existing username, password login

Technical Issue Reporting
#1

here is my code

async function linkwallet(){
  init();
  const out = await Moralis.link(web3.eth.getAccounts().then(e => { 
    return e[0];
   }) , { signingMessage: "Custom Linking Message"})
};

and the error shows that
Uncaught (in promise) TypeError: account.toLowerCase is not a function

and it does not update the table in the server

the step will be 1) signup to Moralis with email and password
2) login
3) link to wallet

#2

Could you Call this function individually and see what response format you’re getting. The link function only accepts a string.

You can take reference from here -
https://docs.moralis.io/moralis-server/users/merging-addresses#linking-elrond-address

#3

its return promise array and I already try with individual call it still the same.

#4

What you get for something like this:

x = await web3.eth.getAccounts();
y = x[0];
console.log(y);
const out = await Moralis.link(y, { signingMessage: “Custom Linking Message”});

[SOLVED] Link metamask/walletconnect after a user is already logged in with username+password
#5

Do you also have latest Moralis SDK version?

#6

I got this error instead

“Uncaught (in promise) TypeError: Cannot read properties of undefined (reading ‘getAccounts’)”

#7

I got “moralis”: “^0.0.54”,

#8

@cryptokid I got this error Uncaught (in promise) TypeError: Cannot read properties of null (reading ‘linkWith’) instead

#12

@cryptokid Oh it work now Thank you :smiley::smiley:

#13

is it gonna be problem if one wallet address can link to multiple user name or should I have some checking on it? with Moralis.link -> it can link 1 wallet address with multiple username.

#14

So, if you link one wallet address with multiple user names, then what happens if you try to authenticate with that wallet address?

#15

I can authenticate both username, so that mean Moralis.link is not have the case to check the accounts that has previously link, right
