Uncaught ReferenceError: React is not defined

[sebastiaanviaene]

When I deploy my electrode app on docker (locally) it builds but when I start it up it says :
Uncaught ReferenceError: React is not defined

My css from the bundle is loaded as I can see it but some components don't work.
Can anybody help me with this problem ? I have succesfully deployed and run a docker image from this project before. I don't know what has changed.

We recently upgraded our Docker Image.
Try referring to the Dockerfile for our Universal-react-node sample app.
Is this error happening while starting the server ? Make sure you have a successful gulp build. The server side rendering mechanism references react files which need to have been transpiled first.

This error is happening when opening the project in the browser, starting the server works fine.
I have recently ( a week ago ) succesfully ran a docker image of my Electrode project but after some work on it i've got this problem. The gulp build has no errors as it is one of my docker build steps and the build works fine.

Is it best to just pull this electrode image and then replace the server + client folders with the ones in my project ?

You can try that, but I can't comment if it will work as is. Does it work in your local following the same commands that you have in the Dockerfile ?

Is there any solution because i am getting the same error when using electrode in prod env.
maybe this is not working correct?

info: Overriding module react-dom with copy optimized for production

This also happens in docker as well as when i am doing same steps as in dockerfile on my local maschine. Both time i am getting Uncaught ReferenceError: React is not defined in my browser console.

That message is concerning server side rendering only. When you see error in browser console, that's client side.

Would you be able to provide sample code that repro this issue?
