blockchain invalid error when syncing a longer blockchain

[koshikraj]

Created 2 nodes,
node1 has 41 blocks created using mineBlock API
node2 has only genesis block
when node 2 is connected to peer node1, it gives following error and fails to replace the blockchain

blockchain possibly behind. We got: 0 Peer got: 41
Received blockchain is longer than current blockchain
Received blockchain invalid

The error is likely to be because of the first condition in isValidChain when called from replacechain.

var isValidChain = (blockchainToValidate) => {
    if (JSON.stringify(blockchainToValidate[0]) !== JSON.stringify(getGenesisBlock())) {
        return false;

Performing a JSON.stringify on an object will not always give the same value as objects are unordered.

Can someone verify this issue?

I have no such issue.

@gentleKun , This issue is due to stringifying the unordered dictionary. May not be reproducible every time. It is always safer to compare the hash value instead which proves the integrity.

I know the question where it is , and i have modified it in my file main.js file.
