Lua: Error during loading on macOS

[imdreamrunner]

Hey guys, I have the following error during launch of the Wireshark.

Lua: Error during loading:
 ...gins/protobuf_dissector/modules/generic/proto_fields.lua:36: bad argument #3 to 'bytes' (Display must be either base.NONE, base.DOT, base.DASH, base.COLON or base.SPACE)

Wireshark version Version 2.4.2 (v2.4.2-0-gb6c63ae).
macOS version 10.12.6 (16G29)

Error message at start up....

Lua: Error during loading:
...otobuf_dissector-master/modules/generic/proto_fields.lua:36: bad argument #3 to 'bytes' (Display must be either base.NONE, base.DOT, base.DASH, base.COLON or `base.SPACE)

macOS version 10.12.6 (16G29)
Wireshark Version 2.4.2 (v2.4.2-0-gb6c63ae)

I got the same error. According to the latest wireshark lua api wiki, just figure out it caused by the update of api(ProtoField.bytes) in certain version after 1.12.0. So the fix is to update the 3 lines to as below in file proto_fields.lua.

36: value    = ProtoField.bytes ("protobuf.value", "Value", base.SPACE, "Field value bytes"),
43: GROUP    = ProtoField.bytes ("protobuf.group", "Group", base.SPACE, "Unknown Group Field"),
44: LENGTH_BYTES = ProtoField.bytes("protobuf.length_delimited_bytes", "Length Delimited Bytes", base.SPACE, "Unknown Length Delimited Field"),

Hope the helpful!

Btw it's also appears on ubuntu 16.04 wireshark=2.4.3-1 too. And @hashtree recipe works!

I got another error
Lua: Error during loading:
.../protobuf_dissector-master/modules/generic/proto.lua:35: bad argument #1 to 'new' (Proto_new: there cannot be two protocols with the same name)

Changing line 35 in proto.lua to this helped:
GenericProto.proto = Proto.new("Protobuf2", "Google Protobuf Format")
