frontend js configuration issue

Thank you for your excellent tutorial. I have a issue with the frontend, in the index.js I don't know how add private keys into the keyprovider.

my keyprovider looks like this:
keyProvider:[[
"EOS5BtL6cQsVzMhuujppUTKmVWFY6EYLrDfdraaQnA2BBJYCrxCCb",
"5KCk5d5pAuack1NiqSxTiJsrAiE6wgLxYHGo6JACpMuFJb39NeG"
],[

"5KELKQohNbdoJ2MRmHPQh6ef7tFWSpBQ1gCpcjkNKER7hWczwCZ"
]
], // Your private ke

when i click the ping button I got this problem:
apigen.js:115 AssertionError {name: "AssertionError", actual: false, expected: true, operator: "==", message: "expecting public or private keys from keyProvider", …}

Thank you for your help!

AssertionError [ERR_ASSERTION]: Invalid public key

when I run "node pingPong.js" ,error occured!

The following is the content of my pingPong.js file.

let EOS = require('eosjs')

eos = EOS.Localnet({
keyProvider:['PW5Jj6BExXZ5cYd6VpKktgEugoF9CGWEjbmgh9am27XsFMuorLffi'],
httpEndpoint:'http://127.0.0.1:8888'
})

eos.contract('child.acnt').then((contract) => {
contract.ping("child.acnt",{authorization:['child.acnt']}).then((res) => {
console.log(res)
})
})
ping smart contract is set to EOS blockchanin, and when I use command line to interact to ping smart contract is ok!
when I run "node pingPong.js" , EOS nodeos didn't receive any message
What's the wrong? what should I do?

STD Exception encountered while processing chain.get_code: unknown key

this is part of frontend/src/index.jsx content.
const EOS_CONFIG = {
contractName: "child.acnt", // Contract name
contractSender: "child.acnt", // User executing the contract (should be paired with private key)
clientConfig: {
keyProvider: ['5KQVzEFg4PbDNtCbdhbfgwfaqQYPNzhjna3ZCm5AzrFZCpeoccg','5KcHE3HF4zAecKWFxBiizG3KBPpkBxbbMDAn1HPeHQZecy69bZy'], // Your private key
httpEndpoint: 'http://127.0.0.1:8888' // EOS http endpoint
}
}
'5KQVzEFg4PbDNtCbdhbfgwfaqQYPNzhjna3ZCm5AzrFZCpeoccg','5KcHE3HF4zAecKWFxBiizG3KBPpkBxbbMDAn1HPeHQZecy69bZy' are owner_private_key and active_private_key respectively.
why nodeos show STD Exception encountered while processing chain.get_code: unknown key?
what should I do?
