Error loading recent blocks: TypeError: cache.get(...).then(...).catch(...).finally is not a function

I've recently upgraded from version 7a88078 (2018-12-09) which is running just fine to the current version.

I get an error on startup:

Error loading recent blocks: TypeError: cache.get(...).then(...).catch(...).finally is not a function

Unable to get basic blockchain data

    If you just started your node, it may still be initializing.
    If your node is already initialized, check your RPC connection info.

Console output:

Loading env file: /home/btc-rpc-explorer/btc-rpc-explorer/.env
Loading RPC cookie file: /home/btc-rpc-explorer/.bitcoin/.cookie

Error 923grf20fge: TypeError: cache.get(...).then(...).catch(...).finally is not a function, error json: {}

However I'm pretty sure the RPC connection info is configured correctly:

# Bitcoin RPC Credentials (URI -OR- HOST/PORT/USER/PASS)
#BTCEXP_BITCOIND_URI=bitcoin://rpcusername:[email protected]:8332
#BTCEXP_BITCOIND_HOST=localhost

#BTCEXP_BITCOIND_PASS=rpcpassword

I think I've tracked down the error to the line below. I'm not a JS programmer though. I don't know what's happening here.

btc-rpc-explorer/app/api/coreApi.js

Line 129 in 4f2a935

cache.get(cacheKey).then(function(result) {

Hey @d3spwn - Thanks for reporting this and doing some investigating. I think the issue has to do with the version of node.js you're running. I think my recent change - be9c3cc - should fix the problem for you by removing the code that requires a newer node.js. Please let me know if you're still seeing the errors. Hopefully this gets you up and running!
