The finalized block alway 0

Follow the README and show such logs. I have no idea why the finalized block is 0 all the time. Does anyone know what happened here?

Polkadot state JSON not parsable

When I run npm start with a Polkadot archive node locally, it results in:

node:buffer:593
    slice: (buf, start, end) => buf.utf8Slice(start, end),
                                    ^
Error: Cannot create a string longer than 0x1fffffe8 characters

    at processTicksAndRejections (node:internal/process/task_queues:96:5) {
  code: 'ERR_STRING_TOO_LONG'
}

NodeJS only allows for strings to be 512 MiB, currently the state of Polkadot seems to be larger that that.
Example file.

There are some async parsing libs, but they are slow and I dont know how to write the state back to disk with them either...

`spec_name` Mismatched

Unable to author block in slot 270671004,. `can_author_with` returned: `spec_name` does not match `Darwinia` vs `Crab` Probably a node update is required!

Can this script backup the whole blockchain?

I tried to run this script, but I found I can only backup the current state, all the blocks since block 1 in the fork chain are different with the original chain, just want to make sure can this script backup the whole blockchain?

Cannot convert undefined or null to object

Hey,
I'm trying to get fork-off-substrate to work with https://github.com/edgeware-network/edgeware-node/tree/erup-5-latest.

I assume it's because I have not added the custom types but, I have imported them into the index.js file(const { spec } = require('@edgeware/node-types');) and that should work. Am I missing something here that causes problems?

How to get rid of the validator set?

Hello!

I'm a member of the Kusama Society and we are developing a dedicated interface as a development plan for the society. We want to create some integration tests and for that we want to run a development node reflecting the state of Society members at some point in time.

I'm trying to run a development chain forked off from Kusama. So far I synched an archived node and created the fork against said node. Apparently all went well, but I'm unable to produce blocks and execute extrinsics. I suppose it's because the chain is waiting for the current Kusama validator set. How do I change the validator set and get control over the chain?

I tried editing fork.json but I don't understand its structure.

Unknown error occurred

I got error message like this when I tried exporting chain state following the readme:
