Error deploying to arena (solved)

I made a small demo app and uploaded server code. But when I deploy it gets a bunch of errors:

Does not look like it finds my server app even though its uploaded

Whats going on here ???

Have you push the "Deploy" button?

Yes. It says its deployed and spits out the log listed above

What's in your "arena.env" ?

NODE_ENV=production

Strange...
Please post a ticket here:

I have the same problem (almost identical server log). If there is any solution for this, I would be glad. I used sample code from this github (https://github.com/colyseus/tutorial-playcanvas-server) and uploaded the "lib" folder which was created after building this project.

Have you tried to remove all files from arena and re-upload & deploy them?
Will you please share the lib folder with me?

I did the same thing and everything goes well:

@coco

I finally got working. I think the issue was in the package.json and the nom install and npm start that runs. Not sure.

But basically i sated from scratch made Arena based server app and deployed the JS output from my lib folder (actually dist folder, i changed that output folder)

But, is working now... thanks for the suggestions :)
