Question: How to decode using .proto file with multiple protobufType?

[rakgupta]

Hello:

I'm trying to use the decode node on a binary object returned by an http get (Tesla Powerwall+ API). The .proto file has multiple "message" types and I can't figure out how to decode those.

The proto file is like this:

`
// Tesla Protocol Buffer definition (tesla.proto)
// Used to decode /api/devices/vitals
//
// Credit and thanks to @brianhealey

syntax = "proto3";

package teslapower;

import "google/protobuf/timestamp.proto";

message DeviceVital {
optional string name = 1;
oneof value {
int64 intValue = 3;
double floatValue = 4;
string stringValue = 5;
bool boolValue = 6;
}
}

message StringValue {
string value = 1;
}

message UInt32Value {
uint32 value = 1;
}

message ConnectionParameters {
optional string ipAddress = 1;
optional string serialPort = 2;
optional string serialBaud = 3;
optional uint32 modbusId = 4;
}

message TeslaHardwareId {
optional UInt32Value pcbaId = 1;
optional UInt32Value assemblyId = 2;
optional UInt32Value usageId = 3;
}

message TeslaEnergyEcuAttributes {
optional int32 ecuType = 1;
optional TeslaHardwareId hardwareId = 2;
}

message GeneratorAttributes {
optional uint64 nameplateRealPowerW = 1;
optional uint64 nameplateApparentPowerVa = 2;
}

message PVInverterAttributes {
optional uint64 nameplateRealPowerW = 1;
}

message MeterAttributes {
repeated uint32 meterLocation = 1;
}

message DeviceAttributes {
oneof deviceAttributes {
TeslaEnergyEcuAttributes teslaEnergyEcuAttributes = 1;
GeneratorAttributes generatorAttributes = 2;
PVInverterAttributes pvInverterAttributes = 3;
MeterAttributes meterAttributes = 4;
};
}

message Device {
optional StringValue din = 1;
optional StringValue partNumber = 2;
optional StringValue serialNumber = 3;
optional StringValue manufacturer = 4;
optional StringValue siteLabel = 5;
optional StringValue componentParentDin = 6;
optional StringValue firmwareVersion = 7;
optional google.protobuf.Timestamp firstCommunicationTime = 8;
optional google.protobuf.Timestamp lastCommunicationTime = 9;
optional ConnectionParameters connectionParameters = 10;
repeated DeviceAttributes deviceAttributes = 11;
}

message SiteControllerConnectedDevice {
optional Device device = 1;
}

message SiteControllerConnectedDeviceWithVitals {
repeated SiteControllerConnectedDevice device = 1;
repeated DeviceVital vitals = 2;
repeated string alerts = 3;
}

message DevicesWithVitals {
repeated SiteControllerConnectedDeviceWithVitals devices = 1;
}
`
If I change the output on the http node to "string", I can see the data but when passing it in as a binary object, the decode node is not able to output a decoded JSON object. If I change the Type in the node to "DeviceVital" (the first message type in the file), I can see the data for that type, but it is not decoded.

Any help would be really appreciated.
