Question

How to fill StringValue in protobuf (programming in python)

message event {
    string id = 1; 
    google.protobuf.StringValue test = 2;
}

Answer 1

event.test.value = 'test'

Also works. It is more straightforward and doesn't require importing StringValue class.

Answer 2

After fighting for a while found the answer

event.test.CopyFrom(wrappers.StringValue(value='test'))
