Unable to read multi array in javascript

Question

Im trying to read an array by using

console.log(myarray[0])
console.log(myarray[0][0])
console.log(myarray[0][1])
console.log(myarray[0].ACCOUNT_PROP_SITE_ID)
console.log(myarray[0]['ACCOUNT_PROP_SITE_ID'])

Whatever I try, the Console.log returns with an error or undefined.

This is the array within console.log that i'm trying to read

console.log array

Any help would be appreciated. Thanks
