Can I transfer EOS from one account to other using eosjs or is EOS only used for buying RAM and staking? (Both accounts are on jungle testnet)

Question

async function sendEos (sender, receiver ) {
 try{
const result = await api.transact({
    actions: [{
      account: 'eosio.token',      //'eosio.token',
      name: 'transfer',                //'transfer',
      authorization: [{
        actor: sender, //'useraaaaaaaa',
        permission: 'active',
      }],
      data: {
        from: sender,
        to: receiver,
        quantity: '1 EOS',
        memo: '',
      },
    }]
  }, {
    blocksBehind: 3,
    expireSeconds: 30,
  });
  console.dir(result);
}catch (e) {
console.log('\nCaught exception: ' + e);
if (e instanceof RpcError)
  console.log(JSON.stringify(e.json, null, 2))}};

Getting error:

Caught exception: Error: assertion failure with message: symbol precision mismatch (node:12620) UnhandledPromiseRejectionWarning: ReferenceError: RpcError is not defined
at sendEos (E:\EOSIO\transactEos.js:45:22)
at process._tickCallback (internal/process/next_tick.js:68:7)

What fields do I need to change? I hope someone can guide me. Thanks in advance!

Answer 1

The EOS precision you have provided here is 1 EOS and that is your error. The typical precision is 1.0000 EOS. If you also want your transaction to be signed and broadcasted to the network:

async function sendEos (sender, receiver ) {
 try{
const result = await api.transact({
    actions: [{
      account: 'eosio.token',      //'eosio.token',
      name: 'transfer',                //'transfer',
      authorization: [{
        actor: sender, //'useraaaaaaaa',
        permission: 'active',
      }],
      data: {
        from: sender,
        to: receiver,
        quantity: '1.0000 EOS',
        memo: '',
      },
    }]
  }, {
    sign: true,
    broadcast: true,
    keyProvider: 'Your private key here',
    blocksBehind: 3,
    expireSeconds: 30,
  });
  console.dir(result);
}catch (e) {
console.log('\nCaught exception: ' + e);
if (e instanceof RpcError)
  console.log(JSON.stringify(e.json, null, 2))}};
