Additional context

When I use the version 4.2.0-beta.0 this issue does not happen and the project work as expected. But in versions 4.2.0-beta.1 and 4.2.0-beta.2 I have the same issue.

Did you create the TypeScript project from zero?

Any workaround?

It's only happening on Docker, everything works fine on my local

Does anyone have a quick fixes for this please ? We will go to production this weekend. Please help.

Thank you very much.

I don't know what's the difference between running yarn develop and yarn start.

On production env we got a empty connection object.

I'm going to lock this, please do not ping random people. v4.2 is a beta release and should only be for testing.

Thank you for taking the time for opening this issue.

We would need more information on this.
Could you provide the content of the tsconfig.json file?
Do you have a build folder in production? Does it contain the compiled code?

I'm getting this after upgrading from 4.2.0-beta3 to 4.2.0. Tried clearing .tmp/node_modules/.cache and rebuilding everything. Everything has been working great on the beta for the last few weeks. Any ideas?
