Using Flat module to flatten circular objects crashes stack

[sgrasso]

Flat doesn't handle circular references in objects correctly. This creates node to blow up running out of heap memory when trying to log.

See Flat issue here.

Perhaps just using the fast-safe-stringify to do a replacer prior to passing it to Flat in the Flatten method.

From fast-safe-stringify's README...

const safeStringify = require('fast-safe-stringify')

function replacer(key, value) {
  console.log('Key:', JSON.stringify(key), 'Value:', JSON.stringify(value))
  // Remove the circular structure
  if (value === '[Circular]') {
    return
  }
  return value
}
const serialized = safeStringify(o, replacer, 2)
// Key: "" Value: {"a":1,"o":"[Circular]"}
// Key: "a" Value: 1
// Key: "o" Value: "[Circular]"
