Error: Cannot find module 'app-endpoint-native

[jschueller]

Hello,

I'm trying to get the demo running on ubuntu 18.04 host, firefox 83, as told in the README.

First I tried to fix the server build with fix from #51 and this patch:

--- a/app-endpoint-server/package.json
+++ b/app-endpoint-server/package.json

   },

+    "westfield-endpoint": "^0.3.2",
     "ws": "^7.4.1"

(seems the "link" keyword is not accepted by npm anymore, and I dont have westfield-endpoint package, trying the npm one)

then I follow the procedure to run the gt3 demo and get the following trace from the server:

Indeed, I can reproduce it here as well. Will investigate.

[Zubnix]

Could you try again with latest master and confirm it is fixed now?

[jschueller]

yes, I still got an error: "Error: Cannot find module './protocol/wl_surface_interceptor'"

[Zubnix]

It seems the protocol generation, tied to the prepare hook, is no longer automatically triggered by an npm install. Unfortunately it was picking up my locally generated sources which hid the error for me. I've enabled it explicitly now and tested on a clean build. Could you try again?

[jschueller]

it works! thanks
