Protobuf Practice

Edit the schema, wait for the descriptor checks, and continue when everything passes.

Progress

1. Field Numbers

Context

Every field needs a numeric tag. That number is what goes on the wire; the name is only for generated code and JSON. These fields are missing theirs.

Task

Assign unique field numbers to id, name, and email so the schema compiles.

schema.proto

Valid Schema

syntax = "proto3";

package practice;

message UserProfile {
  string id;
  string name;
  string email;
}

EVALUATION_CHECKS

The Protobuf schema compiles successfully.

Message 'UserProfile' is defined.

All fields (id, name, email) are assigned unique numbers.

Please satisfy all checks above

Write practical schemas with messages, fields, and types.

Evolve messages without breaking deployed systems.

Decode wire-format bytes one field at a time.
