Ok, so the single and double quotes instead of backslashes, got it.

Also, if I want to sign one key at a time, do I need to set the sighashtype param to 'SINGLE' ?

No, sighash is a way to specify what you actually want to sign, not the keys you want to sign with. See https://bitcoin.org/en/developer-guide#term-signature-hash

no problem. You could also provide the quoted json in this format (escaping the inner quotes): `"[\"privkey\"]"` but I find the above easier to read.

Try this:

You need to provide the private keys and the utxo as arrays and make sure it is valid json and in quotes.
