Question

I m not able to parse that file. and if proto file not accept this character please can share list of character which proto file not accept.

Answer 1

Please find the protobuf documentation on proper syntax for defining messages in protos.

. is used for selecting an attribute of an object in python, so obviously one shouldn't use it in message fields of proto. Instead You can use _ as character for separating words in a single field name.

A small Sample for you :

syntax = "proto3";

message SearchRequest {
  string query = 1;
  int32 page_number = 2;
  int32 result_per_page = 3;
}
