Using Custom Types with Repeated Keyword Doesn't Work
See original GitHub issueBuilding this proto file
syntax = "proto3";
message Car {
string name = 1;
string color = 2;
}
// custom repeated type throws error
message Cars {
repeated Car cars = 1;
}
// primitve type works fine
message List {
repeated string list = 1;
}
throws
/node_modules/typescript/lib/typescript.js:11851
return array.hasOwnProperty("pos") && array.hasOwnProperty("end");
^
TypeError: Cannot read property 'hasOwnProperty' of null

I’ve created a repro here: https://github.com/flolu/protoc-gen-ts-repeated-repro
Basically it seems as if custom Types (in this case Car) doesn’t work with the repeated keyword.

I had the same problem. It seems you need to check the build package deploy in npm. When I built and generated locally, I could use it without any problem.
Looks like it fails while generating the typescript files. It could be easily traced IMHO. I’ll take look at it in a few hours after work.
