I try to put my react application on the server, but when starting npm run build a myth pops up like an error someone has an idea what I am doing wrong if I ask for help, I am grateful for your time

Check the scripts field in the package.json, it seems like you're missing the "build" command declaration there. If the project is created using create-react-app, try adding this: "build": "react-scripts build" and running again — theVoogie

the error say that the build script is missing, so please add the below definition to your script config settings.

"build": "react-scripts build"
