Remove one tag

[IgorRSGraziano]

I'm editing an external protobuf, where I don't have a mapping file, but I know I need to edit the item with tag 1. But if I write the tag, it gets duplicated, how can I remove one?

proto.writeStringField(1, preparedMsg)

After write one field, if i run

proto.readFields((tag, _, pbf) => { if (tag != 1 || !pbf) return; console.log(tag); });

i get twice log of 1
