Schema in question ^

example of object being saved:

const wallet = {
  walletType: 'multi', 
  mnemonic: '...', 
  privateKey: null
}

The privateKey being null crashes it, this is despite the said field not being a required field in the schema.

I have a feeling this may have to do with the type in the schema being string, and null for being a string it errors out, it works fine if you remove the key privateKey altogether
