RPC FundRawTransaction: FeeRate I want to pass feerate argument to Bitcoin Unlimited while using fundrawtransaction.

I tried

fundrawtransaction ["020000000001e80300000000000017a914f65d061c8966ae9d0d6add32879a492d99bce5848700000000" {"feeRate":0.00001}]


However, it says

Error: Error parsing JSON:{feeRate:0.00001}]


How can I pass the feeRate argument like these lines (param0=02000..., param1=feerate) do, but using Core's RPC Debug window?
After a little research, it appears that the syntax is valid for Core (these lines), but Bitcoin Unlimited doesn't have that code.
