invalid encoding starting at

[dtrce]

I'm getting the following error when loading the proto file attached:

** (UnicodeConversionError) invalid encoding starting at <<154, 179, 139, 210, 5, 18, 200, 5, 10, 5, 84, 49, 48, 48, 49, 16, 0, 26, 188, 5, 10, 32, 10, 3, 49, 50, 49, 18, 8, 49, 51, 58, 53, 56, 58, 48, 48, 26, 8, 50, 48, 49, 55, 49, 50, 50, 54, 32, 0, 42, ...>> (elixir) lib/string.ex:1840: String.to_charlist/1 lib/exprotobuf/parser.ex:41: Protobuf.Parser.parse/2 lib/exprotobuf/parser.ex:55: Protobuf.Parser.parse!/2 lib/exprotobuf/parser.ex:10: anonymous fn/3 in Protobuf.Parser.parse_files!/2 (elixir) lib/enum.ex:1826: Enum."-reduce/3-lists^foldl/2-0-"/3 lib/exprotobuf/parser.ex:8: Protobuf.Parser.parse_files!/2 lib/exprotobuf.ex:80: Protobuf.parse/2 expanding macro: Protobuf.__using__/1...

I was able to load the proto file in a sample java protobuf reader to ensure that the file is in the right format. Not sure if I'm missing a config parameter.
