Hi, Not sure what I am doing wrong, less sure about a bug so I have the following output when I try to run a server app using mediasoup: ```auto mediasoup createWorker() +0ms mediasoup:Worker constructor() +0ms mediasoup:Worker spawning worker process: /node_modules/mediasoup/worker/out/Release/mediasoup-worker --logLevel=error --rtcMinPort=10000 --rtcMaxPort=10100 +0ms mediasoup:Channel constructor() +0ms mediasoup:PayloadChannel constructor() +0ms mediasoup:ERROR:Worker (stderr) /node_modules/mediasoup/worker/out/Release/mediasoup-worker: 1: �������H __PAGEZEROx__ TEXT@6@6 __text__ TEXT@: not found +0ms mediasoup:ERROR:Worker (stderr) /node_modules/mediasoup/worker/out/Release/mediasoup-worker: 2: �-@ � __stubs__ TEXT: not found +1ms mediasoup:ERROR:Worker (stderr) /node_modules/mediasoup/worker/out/Release/mediasoup-worker: 3: .b: not found +0ms mediasoup:ERROR:Worker (stderr) /node_modules/mediasoup/worker/out/Release/mediasoup-worker: 5: Syntax error: word unexpected (expecting ")") +0ms mediasoup:Channel Producer Channel ended by the worker process +7ms mediasoup:Channel Consumer Channel ended by the worker process +1ms mediasoup:PayloadChannel Producer PayloadChannel ended by the worker process +8ms mediasoup:PayloadChannel Consumer PayloadChannel ended by the worker process +0ms mediasoup:Worker close() +16ms mediasoup:Channel close() +2ms mediasoup:PayloadChannel close() +3ms mediasoup:ERROR:Worker worker process failed unexpectedly [pid:37, code:2, signal:null] +0ms [2021-07-30T11:21:50.332] [ERROR] server - Error occurred while server is being started Error: [pid:37, code:2, signal:null] at ChildProcess.Worker._child.on (/node_modules/mediasoup/lib/Worker.js:122:43) at ChildProcess.emit (events.js:198:13) at Process.ChildProcess._handle.onexit (internal/child_process.js:248:12) ``` seems like the compiled bin file is problematic. lead me to the conclusion that I compile it somehow wrong. The environment: I try run the server app inside a docker image: `FROM ubuntu:20.04` mediasoup version: 3.8.0 node v10.19.0 gcc 9.3.0 npm 6.14.4 Any idea what I miss? ---

Thank you for your quick reply.

I have a suspicion that due to being on macOS you might have compiled worker on macOS and now trying to run it under Docker. Make sure you don’t include `node_modules` into your Docker context. Can’t tell much more without Dockerfile. ---

From Dockerfile on GitHub: ```auto RUN npm install -g node-gyp COPY ["package.json", "package-lock.json*", "./"] RUN npm install COPY . . ``` This is precisely your problem: you build worker under Ubuntu and then replace it with one built on macOS. Obviously those are different executables. 1. Never use `COPY . .`, copy specific files and directories you need 2. Always include `.dockerignore` and put things like `node_modules` into it 3. Not sure where you’ve got `npm install -g node-gyp` from, but it is not needed here ---

Good finding. I’ll close the issue in GH. ---
