I am a noob with Netlfiy. I am trying to deploy a React app, however I keep getting Command failed with exit code 1 when it gets to the building stage. I’ve tried looking it up in the forums and tried everything I could find but had no luck. However it does build locally with no issues.
I don’t know how to mark this as solved, but I found the issue. The Initialization part gave a warning, I fixed what it warned about and it deployed no issues 
The better the post - the faster the answer.

12:22:39 PM: One of your dependencies, babel-preset-react-app, is importing the
12:22:39 PM: @babel/plugin-proposal-private-property-in-object package without
12:22:39 PM: declaring it in its dependencies. This is currently working because
12:22:39 PM: @babel/plugin-proposal-private-property-in-object is already in your
12:22:39 PM: node_modules folder for unrelated reasons, but it may break at any time.
12:22:39 PM: babel-preset-react-app is part of the create-react-app project, which
12:22:39 PM: is not maintianed anymore. It is thus unlikely that this bug will
12:22:39 PM: ever be fixed. Add @babel/plugin-proposal-private-property-in-object to
12:22:39 PM: your devDependencies to work around this error. This will make this message
