i've got the same problem with the "proof-of-work" property, does anybody solved it?

[cvaldezscse]

I solved this problem, at first you have your coin daemon running properly, and you may be able to launch it methods like i.e.
./yourcoin_daemon getblockcount

if it returns a number, it means that it works properly, so the next step is when you start your explorer at firstfrom the explorer root path with npm start, then run manually the sync.js script, and it will be storing in your mongodb if all the properties are correct,

PD. look in the settings.json file if your wallet credentials are correct

my fix:

add to coin config (yourCoin.conf)

txindex=1
addressindex=1
spentindex=1

@modinfo I did, still get length error.

What it means? run manually sync.js script? Isn't it mean type node scripts/sync.js index reindex ?
