Locktime said "optional" in docs:

It is optional, but since you are using positional arguments instead of named arguments, it must be provided when you want to provide an argument positioned after it. Because you are doing positional arguemnts the parser doesn't know what each position corresponds to if one is missing.

To actually not provide it, you have to use named arguments. That would look like:

Code:

{
   "jsonrpc": "1.0",
   "id": 6,
   "method": "walletcreatefundedpsbt",
   "params": {"inputs": [{
         "txid": "a77564bb72336febc5fe620bc67586dcc014bad6bb1c3aa53e3b01bb6159f241",
         "vout": 0,
         "sequence": 0
      }, {
         "txid": "a77564bb72336febc5fe620bc67586dcc014bad6bb1c3aa53e3b01bb6159f241",
         "vout": 1,
         "sequence": 0
      }],
      "outputs": [{
         "tb1qgz5yfluv3n0sjcadxhmm3dk4xrwlglr88vsj8k": 0.00349723
      }],
        "options": {
         "subtractFeeFromOutputs":[0]
      }
   }
}

Locktime said "optional" in docs:
https://bitcoincore.org/en/doc/0.20.0/rpc/wallet/walletcreatefundedpsbt/
locktime (numeric, optional, default=0) Raw locktime. Non-0 value also locktime-activates inputs

Yes adding locktime did the trick, thank you!

This is the working JSON, combinding both advices, it may helps someone in the future:

{
   "jsonrpc": "1.0",
   "id": 6,
   "method": "walletcreatefundedpsbt",
   "params": [
      [{
         "txid": "a77564bb72336febc5fe620bc67586dcc014bad6bb1c3aa53e3b01bb6159f241",
         "vout": 0,
         "sequence": 0
      }, {
         "txid": "a77564bb72336febc5fe620bc67586dcc014bad6bb1c3aa53e3b01bb6159f241",
         "vout": 1,
         "sequence": 0
      }],
      [{
         "tb1qgz5yfluv3n0sjcadxhmm3dk4xrwlglr88vsj8k": 0.00349723
      }], 0, {
         "subtractFeeFromOutputs":[0]
      }
   ]
}

The argument following the outputs is an integer for the locktime. The options come after that.

Failed with same: "Expected type number, got object"

{

   "params": [
      [{
         "txid": "a77564bb72336febc5fe620bc67586dcc014bad6bb1c3aa53e3b01bb6159f241",
         "vout": 0,

      }
   ]
}

Crypto Swap Exchange

An integer has to be specified in the field, as indicated by your error. Try replacing your string with the vout index of your outputs that you want to deduct the fees from (ie. 0).

Hi,

I am trying to RPC interface with Core and use walletcreatefundedpsbt with the following JSON:

{
   "jsonrpc": "1.0",
   "id": 6,
   "method": "walletcreatefundedpsbt",
   "params": [
      [{
         "txid": "a77564bb72336febc5fe620bc67586dcc014bad6bb1c3aa53e3b01bb6159f241",
         "vout": 0,
         "sequence": 0
      }, {
         "txid": "a77564bb72336febc5fe620bc67586dcc014bad6bb1c3aa53e3b01bb6159f241",
         "vout": 1,
         "sequence": 0
      }],
      [{
         "tb1qgz5yfluv3n0sjcadxhmm3dk4xrwlglr88vsj8k": 0.00349723
      }], {
         "subtractFeeFromOutputs": ["tb1qgz5yfluv3n0sjcadxhmm3dk4xrwlglr88vsj8k"]
      }
   ]
}

It fails with: Expected type number, got object.

But, it works if subtractFeeFromOutputs option is not used, so I assume options should be included somewhat differently.

Unfortunatelly docs or google didn't help me to solve this Sad

Can you please tell my how to modify this JSON?

Thanks
