(Solved) How to get burnproof for unified token unshieldings?

I’m trying to get burning proof of a unified token unshieldings but cannot. I’m getting invalid parameters error raised from here:

github.com

incognitochain/incognito-chain/blob/production/rpcserver/http_bridge_agg.go#L870


	err = json.Unmarshal(rawData, &Reader)
	if err != nil {
		return nil, rpcservice.NewRPCError(rpcservice.RPCInvalidParamsError, err)
	}
	txReqID := Reader.TxReqID
	if Reader.DataIndex != nil {
		txReqID = common.HashH(append(txReqID.Bytes(), common.IntToBytes(*Reader.DataIndex)...))
	}
	height, onBeacon, err := httpServer.blockService.GetBurningConfirm(txReqID)
	if err != nil {
		return nil, rpcservice.NewRPCError(rpcservice.RPCInvalidParamsError, err)
	}
	return retrieveBurnProof(0, onBeacon, height, &txReqID, httpServer, false)
}

I’m sending bridgeaggGetBurnProof method with [{"TxReqID" : 32c4239d18df17acdf76cb34d20e254a905956c0982c341c9232f99661ecac98, "DataIndex": None}] . Should I know DataIndex instead of sending it as None? If so, how can I find out it? Or I’m totally incorrect. Should I use another method? If so, which one?

Thanks.

Hi @abduraman, you can call RPC bridgeaggGetBurnProof with the following payload:

{
"id": 1,
"jsonrpc": "1.0",
"method": "bridgeaggGetBurnProof",
"params": [
    {
        "TxReqID": {{yourUnshieldTxID}},
        "DataIndex": 0
    }
]}

DataIndex is always zero currently.
