No match data when field type is not string

[get109en]

If the field's type is string, everything goes well. But for a field whose type is not string, data can't be matched.
example:
------- pfoto file -------
// The Gripmock service definition.
service Gripmock {
// simple unary method
rpc SayHello (Request) returns (Reply);
}

// The request message containing the user's name.
message Request {
google.protobuf.StringValue name = 1;
}

// The response message containing the greetings
message Reply {
string message = 1;
int32 return_code = 2;
}

with stub
curl -X POST -d '{"service":"Greeter","method":"SayHello","input":{"equals":{"name":"gripmock"}},"output":{"data":{"message":"Hello GripMock"}}}' localhost:4771/add
though below command can run well.
curl -X POST -d '{"service":"Greeter","method":"SayHello",{"data":{"name":"gripmock"}}}' localhost:4771/find

But when I tried grpcrul command like
grpcurl -plaintext -d @ localhost:4770 helloworld.Greeter/SayHello
{"name":"gripmock"}
^Z

Below error occurred.
ERROR:
Code: Unknow
Message: Can't find stub

Service: SayHello
Input
{
name: map[value:gripmock]
}
Closest Match
equals:{
name: gripmock
}

It seems other types except string type, map[value is added to input. Thus data can't be matched.
How to fix it?I tried to send the request by BloomRPC, the same error ocurred.

Input format is defined in stub. You can read for solution here

p/s: Please edit request with style code.
double ` or
double ```

Sorry, I can't find solution in above link https://github.com/tokopedia/gripmock. Can't you tell me in details?
is google.protobuf.StringValue supported?

Sorry for late! You can show me the docker command line that you use? and all steps, file stub you defined, command lines you run... please detail.

Sorry for late. Let me give you some details.
Protofile just like below. It uses google.protobuf.StringValue .

syntax = "proto3";

package simple;

option go_package = "github.com/tokopedia/gripmock/example/simple";

// The Gripmock service definition.
service Gripmock {
// simple unary method
rpc SayHello (Request) returns (Reply);
}

// The request message containing the user's name.
message Request {
google.protobuf.StringValue name = 1;
}

// The response message containing the greetings
message Reply {
string message = 1;
int32 return_code = 2;
}

Then I mock the proto file.
docker run -p 4770:4770 -p 4771:4771 -v /mypath:/proto tkpd/gripmock /proto/hello.proto
And added stub by using below command.
curl -X POST -d '{"service":"Greeter","method":"SayHello","input":{"equals":{"name":"gripmock"}},"output":{"data":{"message":"Hello GripMock"}}}' localhost:4771/add

But when I tried grpcrul command like
grpcurl -plaintext -d @ localhost:4770 helloworld.Greeter/SayHello
{"name":"gripmock"}
^Z

Below error occurred.
