I'm trying to deploy my app on Heroku. I chose Heroku and I'm using the free stuff, I don't know if it has something to do with it, I could have chosen another one. For example, I tried to deploy it on DigitalOcean, and it never ended, so I canceled it after 1 1/2 hours

It seems to be a memory limit problem

If I execute "npm run start" or "npm run build" on my machine, everything works perfectly

EDIT

After searching the internet I found a way to fix the memory limit.

It was adding a new variable to Heroku: NODE_OPTIONS variable, value: --max_old_space_size=1024

But the problem wasn't fixed

Now, the build log is this:

As you can see, the problem has to do with the react version or something like that

Can you tell me how to fix this problem?

The git hub is https://github.com/rafaelsoteldosilva/serenity-sc

In the project, I use: create-react-app, react-three-fiber, styled-components

Thanks in advance
