Unsupported type: <class 'google.protobuf.pyext._message.ScalarMapContainer'>

Hello there!

I have a message in proto file with map parameter:

message BlahRequest {
	enum BlaDataType {
		BLA = 0;
		BLA1 = 1;
		BLA2 = 2;
	}
	BlaDataType Type = 1;
	string Identity = 2;
	string UserSid = 3;
	string ParametersKey = 4;
	map<string, string> Parameters = 5;
	bool BlaDataTables = 6;
	bool BlaIsBla= 7;
}

I'm trying to generate payloads from this proto file like this:

message_fuzzers = protofuzz.from_file(proto_file)
        for obj in message_fuzzers[self.method_name].permute():
        do_some()

but I got an error:

Exception has occurred: RuntimeError
Unsupported type: <class 'google.protobuf.pyext._message.ScalarMapContainer'>

Am I doing something wrong?
