truffle test -> Error: Number can only safely store up to 53 bits

[mezrin]

My test:

var DASToken = artifacts.require("DASToken");

contract('DASToken', function (accounts) {
    const tokenName          = 'DA$ name';
    const tokenSymbol        = 'DA$ symbol';
    const tokenDecimals      = 1;
    const tokenSupply        = Math.pow(10, 9 + tokenDecimals);
    const tokenInitialHolder = accounts[0];
    const tokenContractOwner = accounts[1];

    it("Should test transmission of DA$ tokens", function () {
        const tokensReceiver = accounts[2];
        const amountToSend   = 100;

        var dasToken;
        DASToken.new(
            tokenName, tokenSymbol, tokenDecimals, tokenSupply, tokenInitialHolder, {from: tokenContractOwner}
        ).then(function (instance) {
            dasToken = instance;
            assert.ok(dasToken.address);
            //
            // Contract created, do the test transfer
            console.log('send transaction');
            return dasToken.transfer(tokensReceiver, amountToSend, {from: tokenInitialHolder});
        }).then(function (instance) {
            console.log('transaction finished');
        })
    });
});

Console output:

Contract: DASToken
  ✓ Should test transmission of DA$ tokens

error produced by the line return dasToken.transfer(tokensReceiver, amountToSend, {from: tokenInitialHolder});
in the console I see send transaction but do not see transaction finished

[mezrin]

I found a reason of this problem

to implement my token I used this code (ERC223): https://github.com/Dexaran/ERC23-tokens/tree/Recommended

contract DASToken is ERC223Token, Owned {...}

But ERC223 describes an event Transfer with indexed field bytes indexed data. If remove indexed from parameter type - everything is OK

[assafmo]

This happens because only fixed-size types can be indexed.
i.e. bytes and string cannot be indexed.

Thanks for figuring this out! Cheers!
