pub-sub example: fail to run "Cannot find module"

See original GitHub issue

Error

When running pub-sub example I am getting this error -

internal/modules/cjs/loader.js:905
  throw err;
  ^

Error: Cannot find module '../../../proto/dapr/proto/runtime/v1/dapr_pb'
Require stack:
- /Users/yosi/code/dapr-js-sdk/build/implementation/Client/GRPCClient/binding.js
- /Users/yosi/code/dapr-js-sdk/build/implementation/Client/DaprClient.js
- /Users/yosi/code/dapr-js-sdk/build/index.js
- /Users/yosi/code/dapr-js-sdk/examples/pubsub/dist/index.js

Steps to Reproduce the Problem

> git clone  git clone git@github.com:dapr/js-sdk.git dapr-js-sdk
> cd dapr-js-sdk
> npm install
> npm run build
> cd examples/pubsub
> npm install
>  npm run start:dapr-http

Workaround

I changed the dapr-client dependency to come from npm instead of relative file

Environment info:

node version: 14.18.1
npm version: 6.14.15

Using dapr installed via homebrew -

CLI version: 1.4.0
Runtime version: 1.4.3

Found the issue - https://github.com/dapr/js-sdk/blob/master/scripts/build.sh#L31

We are doing - cp -R ./src/proto/ ./build

In mac, it copies the contents of ./src/proto to build directory, while in linux (tested on popos) it copies the proto folder to build.

js-sdk on  master [!] is 📦 v1.0.2 ❯ ls build
js-sdk on  master is 📦 v1.0.2 ❯ cp -R ./src/proto/ ./build
js-sdk on  master is 📦 v1.0.2 ❯ ls build
dapr  google

As you can see, there is no proto directory, there are dapr & google which are contents of src/proto

If I removed the / (./src/proto/ -> ./src/proto) it works correctly -

js-sdk on  master is 📦 v1.0.2 ❯ rm -rf build/*
zsh: sure you want to delete all 2 files in /Users/yosi/code/dapr/js-sdk/build [yn]? y
js-sdk on  master is 📦 v1.0.2 ❯ cp -R ./src/proto ./build
js-sdk on  master is 📦 v1.0.2 ❯ ls ./build
proto

To test it works correctly, did the change in scripts/build.sh and now the example is working 🎉
