Windows 10 x64

im using tsc (Typescript compiler)
In order to generate the .ts files from the .proto im using the command protoc --plugin option with the protoc-gen-ts plugin

What did you do?
Steps to reproduce the behavior:

  1. create a protobuf file that contains a repeated enum message
  2. Send a Protobuf binary from my Android App to my Nodejs Express Server
  3. Attempt to deserialize the buffer in my Express Server

What did you expect to see
a Protobuf Object

What did you see instead?
AssertionError on the repeated enum field.

Make sure you include information that can help us debug (full error message, exception listing, stack trace, logs).
my custom repeated enum field is repeated Amenities amenities = 22; and another one at =23;

Direzione di ricerca

Inizia riproducendo il problema degli enum ripetuti e analizzando lo stack trace in google-protobuf.js, in particolare BinaryReader.readPackedField_ e readPackedEnum. Ispeziona il deserializzatore generato in dist/protobuf/generated/apartment_pb.js e testa il binario fornito con campi enum ripetuti. Il lavoro è completato quando il buffer viene deserializzato in un oggetto Protobuf senza l’AssertionError.
